Work Text:
The Fuuka island was small enough that everyone knew the sound of the evening waves by heart. The streets were quiet after sundown, lanterns flickering in gentle amber light, and in a little wooden house tucked between a bakery and a carpenter's shed lived two people who didn't share blood but shared something far stronger.
Inside that home, a young woman moved through the kitchen with practiced grace. Robin—twenty-one years old, tall, calm, with eyes too soft for how hard she worked—set down a pot of soup on the table. Her apron was still dusted with flour shavings from the library's archive room, she hadn't even changed out of her work clothes yet.
There was a thump upstairs.
Then another.
Then a crash.
Robin sighed into her hands. "Luffy... what did you break this time?"
A black-haired boy poked his head down the stairs, cheeks puffed out like he'd been caught stealing fruit.
"Nothing!"
Robin raised one eyebrow.
"...A little nothing," he amended more quietly.
She smiled despite her exhaustion. "Come down, please. Dinner's ready."
Luffy thundered down the stairs like an excited puppy, nearly tripping on the last step. Life with him was always loud, a storm in tiny human form, but Robin had grown used to it. In truth, she preferred it to the suffocating silence she once lived with.
The two sat together at their wobbly wooden table. Luffy immediately inhaled his soup like he hadn't eaten since the dawn of time.
"Slow down," Robin reminded gently, touching his wrist before he face-planted into the bowl. "Chew."
"But it's good!"
"I'm glad, but I would appreciate it if you survived dinner."
Luffy snorted a laugh and nearly choked, proving her point entirely.
Robin, exhausted as she was, smiled again.
This was their rhythm: hectic, imperfect, but warm.
After dinner, Robin cleaned the dishes while Luffy tried to "help" by drying them, only to drop two plates and absorb the third with his face like a sponge.
When everything was finally put away, Robin straightened her back, winced, and rubbed her shoulder. The two jobs were draining her; the library in the morning, the bar at night. But she glanced over at Luffy, who was stretching his arms like he was preparing for battle with an invisible enemy, and the tiredness in her eyes softened.
"Time to study," she called.
Luffy froze mid-stretch. He slowly looked toward the table like it was a giant sea monster waiting to swallow him whole.
"Do we haaave to?"
"Yes."
"Buuut—"
"Luffy."
He deflated instantly. "Okay..."
The ten-year-old boy sat down with his workbook, tapping the pencil like it was an enemy he wasn't sure he could defeat. Robin settled beside him, leaning her cheek on her palm.
"Let's start with reading tonight," she said softly. "Just one page."
"One?" he blinked. "How about half a page? A quarter?? Just the title???"
Robin chuckled hearing her little brother bargain.
"One page," Robin said, unshakeably.
Luffy grumbled but started reading. Slowly. Painfully slowly. His lips moved with each word, his brows furrowed like he was solving the ancient secrets of the universe.
Halfway through the page, he let his head slump sideways... right onto Robin's arm.
"I don't like this," he mumbled into her sleeve.
"I know," she murmured, brushing his hair back out of his eyes. "But you're doing well. I'm proud of you."
He perked a little at that, cheeks faintly warm. Luffy didn't care about studying, but he cared about making Robin happy more than anything.
And Robin... Robin lived for these quiet moments. Even when exhaustion tugged at her bones, even when her eyelids drooped, she never snapped at him. Never rushed him. Never made him feel small for struggling.
She waited while he traced the words with his finger. She repeated things as many times as he needed. She whispered encouragements when his brain fogged over.
Eventually the page was finished. Luffy slumped dramatically across the table.
"I'm dying."
"No, you're not."
"Maaaaybe a little."
Robin gently poked his cheek. "You survived. Well done."
He grinned proudly. "I'm strong."
"Yes," she agreed, amused. "You certainly are."
They cleaned up the study materials together, Luffy humming a nonsense tune while Robin folded the workbook closed. When everything was done, the two settled near the window, listening to the distant sound of waves.
Robin leaned her head back and exhaled, shoulders finally relaxing for the first time all day. Her eyes fluttered half-closed. Luffy scooted closer until his head bumped her arm again.
"Are you tired?" he asked softly. It wasn't often he dropped his cheerfulness long enough to notice things like this.
"I'll be alright," she assured him, brushing his cheek with her fingertips. "Tomorrow I don't have my morning shift."
Luffy's eyes brightened instantly. "So we can play?"
"We can," she chuckled. "But first, I need to buy groceries."
"Oh!"
Luffy sat up straighter, excitement bubbling out of him like carbonation.
"Robin," he asked, small and hopeful, "can I go with you?"
Robin smiled, the kind of smile that held both gentleness and love.
"Of course," she said. "Tomorrow, we'll go to the market together."
Luffy grinned so wide he nearly toppled sideways. Robin laughed quietly and pulled him close, resting her cheek on top of his head.
In their little house, on their quiet island, the night settled softly around them.
And for a moment, everything felt perfect.
✦ 🍖 📚 ✦
Morning sunlight spilled across the small town of Fuuka Island, warm and golden, carrying the mingled scents of saltwater and fresh bread. The streets were already alive with vendors setting up their stalls: fishermen gutting their early catch, grandmothers bargaining over vegetables, seagulls screaming dramatic opera from the rooftops.
Through all that noise, Robin and Luffy walked hand-in-hand.
Robin held the grocery list in one hand, Luffy's tiny palm in the other. He swung their arms wildly as they walked, humming a tune only he understood. Every few steps, he'd hop on one foot for no reason at all. She steadied him every time he nearly toppled.
"Slow down, Luffy," Robin laughed softly. "We're not racing."
"We could race!" Luffy declared, eyes sparkling. "I'd win!"
"You absolutely would," she said with a fond smile, "but we still need to buy eggs."
"Eggs don't run away!" he protested.
"Maybe not," she replied, "but we still need to catch them."
Luffy gasped dramatically. "Egg-hunting!! Let’s go!!"
Robin snorted before she could stop herself. Life with him was like that, chaotic and loud, but filled with a kind of joy she had thought she'd never get to feel again. She squeezed his hand, and he squeezed back, swinging their arms even harder as if powering a ship.
They turned the corner, and the wet market stretched out before them in its colorful, messy glory. Robin guided Luffy carefully between the stalls, exchanging polite greetings while Luffy bounced at her side.
After buying vegetables, rice, and a suspiciously good deal on meats because Luffy made the seller laugh, the two headed toward the town's main street.
That was when Robin slowed.
Luffy blinked up at her. "Robin?"
But she wasn't looking at the street anymore. She was looking at a bookstore window.
Displayed in the center was a thick, beautifully bound history book, its cover a deep navy blue, embossed with gold lettering that shone under the sunlight. A small sign beneath it read:
"NEW RELEASE! Most Comprehensive History of the West Blue (Year Edition). Limited copies."
The book looked expensive. Very expensive.
Robin's eyes softened in that way she rarely let anyone see, except Luffy, who noticed everything when it came to her. Her fingers tightened slightly around his hand before she let go, just to reach out and touch the glass lightly, almost unconsciously.
She didn't realize she'd stopped walking. She didn't even realize she was staring. She only realized the price tag after a moment.
Robin inhaled her breath softly but still loud enough for Luffy to hear.
Then she sighed, long and quiet, the kind that slipped out when someone wished for something they knew they couldn't afford. Gently, she placed her hand on Luffy's shoulder and steered him away.
"Come on," she said warmly, "we still need flour."
But her voice had that soft ache beneath it, the kind Luffy wasn't used to hearing.
He looked back as they walked, eyes fixed on that navy-blue book glimmering in the sunlight. Something squeezed inside his tiny chest.
The rest of the trip went normally, at least on the surface.
Luffy still hopped on stones, still nearly collided with a fruit cart, still begged for a snack and got distracted by a cat. But every few minutes, his mind wandered back to the bookstore window.
Back to the way Robin sighed. Back to how her eyes had lingered.
By the time they reached home, Luffy's smile had shrunk into something quieter. He helped Robin put away groceries, humming halfheartedly.
Then, when she turned her back to start preparing lunch, he slipped away silently. Up the stairs, into his little room, and closed the door.
The room was small and messy, with drawings taped crookedly on the walls and a pillow shaped like a meat bone. Luffy sat on the floor in the middle of it, legs crossed, brows furrowed in deep thought, which was a rare and dangerous phenomenon.
Robin wanted that book. She wanted it badly, but she didn't buy it.
Because of him.
Because she always put him first.
Luffy clenched his little fists. He didn't like that. He didn't like the look she had given the book, that soft longing she tried to hide with a smile. Robin didn't ask for much. She never asked for anything, actually.
And she deserved something nice. Something really nice.
"Her birthday..." Luffy whispered to himself. "It's soon..."
If he could give her that book... it would make her so happy. He knew it.
But he didn't have money. Not even close.
Luffy stared at the corner of his room where tiny treasures were piled. A few seashells, three foreign coins he found on the beach, and a sparkling shard of glass that he thought was a jewel. None of it would buy even a single page of that history book.
He pressed his palms against the floor.
"I gotta do something..." he muttered.
He thought hard. Harder than he had during any study session. Harder than when he'd tried to count past twenty without skipping fifteen.
Then it hit him.
A spark lit behind his eyes. "I'll get a job."
And with that, the decision carved itself into his heart.
Robin had taken care of him since he was a toddler. Now it was his turn.
And tomorrow... he would start.
✦ 🍖 📚 ✦
Gentle, morning light filtered through the kitchen window, painting soft gold onto the wooden table. Robin tied her hair back as she packed her lunchbox, moving quietly so she wouldn't wake the neighbors. Luffy sat on a stool, swinging his legs while inhaling a bowl of rice like it was a life-or-death mission.
Robin reached over and wiped a stray grain from his cheek. "Luffy, I'll be at the library until late afternoon," she said, voice gentle. "Be good, alright?"
"I'm always good!" Luffy declared proudly, which was… debatable.
Robin kissed his forehead anyway. "I'll see you tonight."
She picked up her bag, gave him one last soft smile, and stepped out the door, pulling it closed behind her.
Luffy listened to her footsteps fade.
Waited.
Waited...
And the moment he was sure she was gone, he shot straight up like a launched cannonball.
"It's time!!!"
He grabbed his little satchel, stuffed it full of nothing useful, and scrambled out of the house.
Today was the day he would become...
A working man (or boy.)
The streets were still waking up. Shops unlocked their shutters, fishermen called out their fresh catches, and sleepy townsfolk began their morning routines.
Luffy jogged down the main road, scanning every storefront.
He spotted a bakery first. He ran up with a huge grin.
"Heya! Do you need workers??"
The old baker stared at him for a second before answering, "yeah, sort of. Why you ask, boy?"
"How about hiring me?" Luffy asked, his grin still plastered on his face.
"You?" The old man blinked. "You're just a little boy."
"But I'm strong!" Luffy boasted. He then tried to lift a tray full of freshly baked pastries to prove it and dropped it immediately.
Pastries were scattered everywhere.
"OUT OF MY SHOP, YOU BRAT!" the baker barked angrily as he kicked Luffy out.
Luffy stuck his tongue out at the angry baker and ran away.
Strike one.
Next, he tried the fish stall.
"Can I work for you?"
The fisherman stared. "Kid, I saw you scared the fish earlier just by sneezing."
"No, I'm not."
"Yes, you are."
Luffy pouted and left.
Strike two.
He tried the tailor shop, but they said he'd poke someone's eye out with a needle.
He tried the carpenter, who said Luffy might glue himself to the floor.
He tried the flower stall, but the lady said he'd eat the flowers.
(This was a valid concern.)
Strike three, four, five.
Luffy sat on a crate, cheeks puffed out in frustration. "Geez... this is hard..."
Then he heard rustling.
He turned to see a man lifting baskets of oranges into a small wagon. The orchard owner was a burly man with sunburned cheeks.
"I could use another pair of hands..." he muttered as he wiped his forehead.
Luffy sprang up like a startled crab.
"I HAVE HANDS!"
The man startled. "W-where'd you come from?!"
"Hey, hey, can I work?? I'm strong!! I can lift things!! And run! And jump! And I don't break that many things anymore!"
The man stared at him for a long moment.
"Aren't you a bit... too young?"
"I'm TEN!!!" Luffy declared proudly, as if that somehow proved he was a fully qualified adult.
The man sighed and rubbed his temples. "Well... I guess I do need help harvesting. It's a very taxing job, and the pay's small, but it's honest work."
Luffy lit up like fireworks. "I'll do it!!!"
And just like that, he had his first job.
The days that followed blurred into a whirlwind of effort.
Working as a fruit picker turned out to be a perfect fit for Luffy, who had the agility and high energy of a young boy. He climbed trees with ease, scooting out on branches like a monkey. He filled basket after basket with oranges, dropping only a few. (Most of the ones he dropped hit him on the head. He ate those.)
The orchard owner shook his head but couldn't help smiling. "You're a strange kid… but you work really hard."
"Shishishi," Luffy grinned, leaves stuck in his hair.
Every day he worked so hard. The other pickers even joked that he was "stealing their share" every time the black-haired boy finished picking from one tree and prepared to jump to the next one.
But despite the chaos that Luffy sometimes caused, they liked his enthusiasm. Belly coins piled slowly in his pocket.
His enthusiasm for work always earned him praise from other workers, and slowly but surely, word spread to other villagers.
Luffy then began to receive several other odd job offers. From lifting crates to delivering newspapers to cleaning the wet market. Every offer that came his way, he accepted with eagerness in his heart and a sparkle in his eyes. The more work he did, the more money he earned.
So Luffy worked, worked, and kept working. Not once did the boy complain, let alone want to quit.
All for Robin's smile.
By the end of each day, Luffy stumbled home absolutely exhausted.
Robin often arrived shortly after him. She'd find Luffy sprawled on the floor or table like a jellyfish thrown ashore.
"Luffy, are you alright?" she'd ask, worried.
"Yeaahh... just... tired... from playing..." he mumbled, melting into the furniture.
Robin smiled, smoothing his hair. "You really should pace yourself when you play."
"Mmhm..." he hummed, eyes already drifting shut.
She never suspected a thing.
Every night, after she fell asleep, Luffy tiptoed into his room and dumped the coins from his pockets onto the floor. A few clinked, rolled, and spun in little circles.
He gathered them in both palms, eyes shining with a soft, stubborn determination.
"I'm gonna get that book..." he whispered to himself.
He dropped the coins into a cloth pouch he hid beneath his bed. It wasn't much yet, but every day it grew.
Every day, he worked harder.
Every day, he imagined Robin's smile.
"I'll make enough… I'll get it for her," he whispered the same promise every night as he collapsed into bed.
The secret mission continued. And Luffy's stash of coins continued to grow.
✦ 🍖 📚 ✦
Three weeks passed in a blur of sweat, bruises, and stubborn determination.
Every morning, after Robin left for work, Luffy dashed into town like a tiny whirlwind. Every evening, he dragged himself home, barely able to hold his head up. And every night, he added more coins to the pouch under his bed.
The pile grew. Slowly at first, then faster.
One afternoon Luffy was on his way home, he had just finished his last work. As of today, he was no longer a "working boy."
He rummaged through his pocket and counted the coins he just earned from his last work, eyes sparkling brighter than any treasure on the Grand Line.
Finally, he had enough. Enough to buy the book.
His heart hammered with excitement. He could already imagine Robin's face when she saw it. He jumped in pure joy.
Tomorrow.
Tomorrow was the day.
Luffy stuffed all the coins carefully back inside his pocket and ran faster when he saw his small house from a distance. A wide, proud, and ready-to-burst smile was etched on his face the whole way.
I'll add them to my savings!
Grinning, the boy opened the front door and ran upstairs. When he pushed open his bedroom door, he froze.
Robin was standing there.
In his room.
Holding the pouch.
His pouch.
Her expression wasn't angry. That would have been easier to handle. Instead, she looked... tired. Sad. And deeply hurt in a way Luffy didn't understand yet.
"Luffy," she said quietly, "what's this?"
His heart lurched into his throat.
"R-Robin?! What're you doing home? You're supposed to be at the library!"
"I took an early leave." Her voice was soft, but there was an edge beneath it. "Someone in town told me they saw you working. Running around carrying heavy crates. Falling asleep on your feet."
Luffy swallowed hard. His fingers curled into fists.
Sensing his reluctance to answer, Robin stepped closer, kneeling so her eyes were level with his. She held the pouch gently, like she was afraid it might break, or that he might.
"Why?" she asked. "Why are you doing all this? You've been exhausting yourself... lying to me... and hurting yourself."
Her voice trembled at the end. "Why, Luffy?"
The boy opened his mouth. The answer sat on the tip of his tongue.
For your birthday. For the book.
Because you always choose me, so I wanted to choose you.
He could have said it. He almost did.
But then he pictured Robin's face when she opened the gift. Her surprise, her joy. Something childish but earnest inside him refused to let that moment go.
"I... I can't tell you."
Robin blinked. "Luffy—"
"I just can't, okay?!" He snapped, fists clenched even tighter. "It's a secret!"
Robin's brows knit. "A secret that's making you come home covered in dirt? With bruises? Falling asleep during dinner? You think I wouldn't notice?"
Luffy's chest tightened; he hated that tone, that hurt.
"I'm fine," he muttered. "I'm strong."
"That's not the point." Her voice rose, not in anger, but in fear she was struggling to hide. "You're a child. You shouldn't have to do this. If we needed money, you should've told me."
"It's not for money!" Luffy shouted before he could stop himself.
Robin froze.
"Then what is it for?" She asked, voice barely above a whisper.
Luffy's mouth clamped shut. His throat burned. He shook his head violently, tears stinging his eyes.
"I can't say!"
Robin exhaled shakily. "Luffy, I'm not mad at you for wanting to help. I'm upset because you didn't trust me enough to tell me. You're hurting yourself, and I—!"
Her voice cracked.
Something inside him cracked with it.
"I DO trust you!" He yelled, voice shaking. "But you're not listening!"
"And you're not talking," she returned, stepping forward. "I'm trying to understand—"
"No, you're not!"
Luffy snatched the pouch out of her hands, clutching it to his chest. His breathing was fast and uneven. His heart pounded so hard it hurt.
"Luffy—stop," Robin said gently, reaching for him.
"No!!"
He stumbled back.
His tears finally spilled.
"I'm trying to do something GOOD!" he cried. "And you're ruining it!"
Robin flinched, her expression shattering.
Something ugly twisted in his stomach. He didn't want to hurt her. He didn't want to say that. He didn't mean it. But the panic was too big, too loud, too tight to swallow.
Before Robin could say another word, he dashed toward the door.
"Luffy, wait—!"
He didn't. He bolted down the stairs, feet slamming against the wood.
"Luffy!!" Robin’s voice echoed after him, frantic.
But he didn't stop. Couldn't stop. Not when his chest felt like it would explode. Not when the world blurred behind tears. Not when fear and frustration tangled in his throat.
Luffy burst out the front door and into the street, clutching the pouch of coins like a lifeline.
Robin called his name again.
He kept running.
Away from the house. Away from the hurt in her voice. Away from everything he didn't know how to say.
He didn't look back. He couldn't.
And for the first time since living with Robin, Luffy felt truly, painfully lost.
✦ 🍖 📚 ✦
Luffy didn't know where he was running.
Only that he had to run.
His feet pounded against the dirt roads, kicking up dust as he tore through the late-afternoon bustle of town. People glanced at him, some startled, some annoyed, but Luffy hardly saw any of them. His vision was blurry from tears, from panic, from the awful tight feeling choking his chest.
The boy clutched his pouch so hard his knuckles turned white.
The coins inside rattled with every step.
Clink, clink, clink.
Each sound stabbed at him.
He kept hearing Robin's voice.
"You're hurting yourself..."
"You didn't trust me..."
"Why, Luffy?"
"I do trust you," he whispered to himself, stumbling forward. "I always do..."
The more he thought about it, the more everything inside him twisted into knots. Shame. Fear. Anger. Regret. It all mixed together until he couldn't breathe right.
He passed the market street. He passed the old well. He ran until the warm lights of the main road faded and the noisy crowd thinned behind him.
The world grew dimmer.
Quieter.
Colder.
Luffy slowed down near a narrow alley, pressing his back against the wall as he hugged the pouch against his chest. His breath came out in shaky bursts.
"Stupid," he muttered to himself, wiping his face with the back of his hand. "Why did I say that to Robin...?"
He didn't want to cry anymore, but the tears kept welling anyway.
I just wanted to make her happy...
He squeezed his eyes shut.
Then, he heard them.
Heavy footsteps and slurred laughing.
"Oi, oi, look at that, would ya?"
"Little brat's holding something."
"Out here all alone, too."
Luffy stiffened.
Three men stepped out from the shadows. They were older, unshaven, and swaying slightly from the smell of cheap booze. Their eyes gleamed when they spotted the pouch in Luffy's arms.
"Whatcha got there, brat?" one of them slurred.
"Nothing!" Luffy hugged the pouch tighter.
"Aww, c'mon," another chuckled darkly. "We just wanna see what you're hiding."
Luffy's heart pounded so hard it hurt. Robin always warned him to avoid a fight with adults. Especially if they were drunken men.
He tried to turn and run, but a rough hand yanked him back by the collar.
"Gotcha."
"Let me go, you stinking old geezer!!" Luffy barked, kicking and thrashing.
"Whaddya say?!"
The man slammed him against the wall, knocking the breath right out of him.
The pouch fell from Luffy's arms, hitting the ground and making an obvious clinking sound for those men to hear.
"Well, well," one thug grinned as he snatched the pouch and took a look inside. "Looks like the brat's been saving."
Luffy stood up and reached out desperately for the money.
"Don't! Give it back!!"
A heavy boot kicked him right on his chest, sending him flying and hitting the wall again.
Luffy grunted in pain.
The men laughed.
"Aww, hear that? He's ordering us."
One of them swung his foot again, this time kicking Luffy across the ribs. The world jolted. Luffy tumbled onto his side, gasping, clutching his stomach.
He wheezed but managed to get on his feet and put up a fight. He needed to get his money back no matter what the cost.
But there was only so much of a fight a little boy could put up against three adult men.
Provoked by his stubbornness, they kept kicking, punching, and slamming him. Clearly didn't have any morals whatsoever since they had no qualms about hurting a little kid.
Through the ringing in his ears, he heard them talking to each other.
"Heh, jackpot."
"Easy money."
"Stupid brat should've kept it hidden."
Luffy forced himself up onto his elbows, vision swimming.
"Give... give it back," he whispered hoarsely. "That's... that's for Robin..."
One of the men crouched down and grabbed Luffy's jaw roughly, lifting his face.
"Still talkin' huh?"
The man smirked.
Then swung.
Knuckles connected with Luffy's cheek, snapping his head to the side. His vision burst with white spots. The ground lurched beneath him.
He felt himself falling.
Falling...
His limbs wouldn't move right. His breaths came out shallow and shaky. The sounds around him grew muffled, like someone was closing a door on the world.
The sound of a pocket jingling with his hard-earned coins gradually faded as the thugs walked away.
Luffy tried to reach out. His fingers barely twitched.
Robin...
His eyes drooped, heavy and burning.
I... I just wanted to give you something special for once...
The darkness crept in.
But in the end I couldn't give you anything...
His last thought was Robin's broken whisper of his name inside his fading mind.
✦ 🍖 📚 ✦
There was warmth... and softness.
A quiet, steady tick... tick... tick somewhere nearby.
Luffy's eyelashes fluttered, heavy and stuck together. He groaned, turning his head just a little. Everything ached. His ribs, his arms, even his fingers throbbed as if they were burning under his skin.
Then... he heard a shaky breath and a muffled sob.
Luffy's eyes opened fully.
And right in front of him, slumped over the edge of the clinic bed, was his sister, Robin.
Her shoulders trembled as she clutched his small hand like it was the last tether she had.
"Robin..??" Luffy croaked.
Her head snapped up instantly.
"Luffy!"
She threw her arms around him before he could even sit up. Her embrace was firm, almost too tight, but full of warmth that made his chest sting worse than any bruise. She buried her face against his shoulder, tears soaking through his shirt as she held him like he might disappear.
"You scared me," she whispered. "You scared me so much..."
Luffy blinked, stunned.
Robin... crying?
His throat tightened. "I'm... I'm sorry..."
He tried to raise a hand to return her hug but winced. Robin immediately loosened her grip, brushing his hair out of his face.
"Don't move too much. Your body is all bruised." Her voice cracked. "Luffy... why were you out there? Why didn't you tell me anything?"
Luffy's lip wobbled.
He didn't want to cry again. But everything hurt, and Robin looked so heartbroken, and his chest was tight with all the secrets he'd been carrying for weeks.
"I... I w-wanted to buy you that book," he whispered.
Robin froze.
"That big new one in the bookstore," Luffy continued quietly. "The one you looked at. I saw your face. You really wanted it. So I saved money. A lot. I worked… worked really hard…"
Robin covered her mouth, eyes brimming again.
"I didn't want you to know 'cause... 'cause it's for your birthday," he sniffed. "And then you got mad at me... and I didn't want to say anything or I'd ruin the surprise... but in the end it's all ruined... my money got stolen..."
Robin leaned close, forehead against his.
"Luffy..." her voice shook. "I wasn't angry because of the secret. I was scared. You were exhausted every night. You were hurting yourself for something I never asked you to do."
"Sorry," Luffy whispered. "I didn't want to worry you..."
"And I shouldn't have raised my voice," Robin said softly. "I was wrong too. I'm so sorry."
She cupped his cheek, brushing away a tear with her thumb.
"You mean so much more to me than any book. I wish you understood that sooner."
Luffy sniffled again.
"I just wanted to make you happy..."
"You did," she murmured, kissing his forehead gently. "You always do. Not with gifts, just by being here."
Before Luffy could answer, a gravelly voice interrupted.
"Well," the clinic doctor grunted from the corner, "seems you two sorted things out."
They both turned.
The old man stood with his arms crossed, beard as white as clouds and posture slightly hunched, but his eyes were sharp and kind.
"Doctor Reya—" Robin stood up from her seat abruptly.
"It's alright, Robin," he said, signaling Robin with his hand. "Ah, also, don't worry about the payment. It isn't needed. That boy's been working himself half to death already, from what I heard."
Robin bowed her head gratefully. Luffy tried to sit up straighter.
"But," the doctor added, pointing a finger, "you, Luffy," his gaze pinned Luffy in place, "stop risking yourself. If you want to grow strong, do it the right way. Not like that."
Luffy gulped and nodded quickly.
"Yes, sir..."
"Good. Then get on home. Slowly."
Robin wrapped an arm around Luffy as she helped him off the bed. He wobbled a little, but she steadied him immediately.
They stepped outside into the late-night light, serene and glowing. The air smelled of the sea. They walked side by side, close enough their shoulders brushed. After a few steps, Luffy glanced up shyly.
"Robin... I'm so sorry," he mumbled. "I couldn't get your birthday gift after all."
Robin stopped walking. She knelt down, one hand gently resting on his cheek as she smiled softly, her eyes radiated warmth and love that wrapped around him like a blanket.
"Listen to me," she whispered.
"You're enough, Luffy."
Luffy's eyes widened. Then slowly, he smiled back.
And hand-in-hand, they walked home together.
✦ 🍖 📚 ✦
The next day, their little house smelled like something sweet.
Luffy had tried his absolute hardest not to burn the tiny sponge cake he mixed altogether by hand, and though it leaned slightly to the right and had a suspicious crack on top, Robin looked at it the way people looked at miracles.
A single candle flickered in the soft light of dusk, casting a warm glow across the small table. There were only two chairs, two mismatched plates, and a few flowers Luffy stole from the neighbor's front yard.
"Happy birthday, Robin!" Luffy beamed, proudly puffing his chest.
Robin laughed softly, brushing a hand over his hair. "Thank you, Luffy. You worked very hard on this."
"Shishishi, baking a cake surprisingly doesn't take a lot of work. It just... cooks itself."
She raised a brow, amused.
They sat side by side, the candle wavering like it was listening to their little celebration. Luffy leaned forward excitedly.
"Make a wish! Make a wish!"
Robin brought her hands together, eyes soft as she gazed at the tiny flame. But just as she inhaled, there was a knocking sound on the door.
Both of them stared at each other.
Luffy blinked. "Who's that?"
Robin stood, smoothing her skirt before heading to the door. She opened it just an inch and blinked in surprise.
There stood an elderly woman with kind, gentle eyes and a paper-wrapped package held carefully in both hands. Her gray hair was tied into a neat bun, and she wore an apron dusted lightly with ink stains.
"Good evening, dear," the woman greeted with a warm smile. "Forgive me for coming unannounced."
Robin straightened politely. "May I help you?"
"I believe," the lady chuckled, "that I may be the one helping you."
She looked past Robin at Luffy, who peeked from behind her like a curious puppy.
"Ah! There he is," she said, amused. "The little shadow who keeps running away from me."
Luffy jumped. "I wasn't running! I was just... moving rapidly in the opposite direction!"
The woman laughed, shaking her head.
"Young man, every time you passed my window, you stared at the same book. Then the moment I stepped outside to call you in... poof! You vanished."
Luffy puffed his cheeks and hid behind Robin again.
Robin blinked, slowly understanding.
"The book...?" she murmured.
"Yes." The lady lifted the wrapped package. "This one."
She offered it with both hands, her expression tender.
Robin hesitated. "Ma'am, we... we can't possibly afford—"
"Oh, it's not for sale," the woman interrupted gently. "It's a gift."
Robin inhaled softly.
The lady continued, her voice warm with memory.
"A few months ago, I dropped my lunch in the middle of a very crowded street. Everyone just walked around me, except you."
Robin's eyes slightly widened hearing that.
"You knelt down, picked up what could be saved, and gave me your own meal. You told me not to worry about you and hurried off so you wouldn't be late for work."
Robin's hand flew to her mouth in realization.
"I never forgot that kindness," the woman said. "I always wanted to return it. But I didn't know your name or where you lived. Then I saw you walking with this young boy, looking at the window display of my shop."
She chuckled softly.
"I rushed out to greet you, but you two had already disappeared again."
"We walk fast!" Luffy said defensively.
The woman winked at him. "Yes, I noticed."
Then she gently pressed the package into Robin's hands.
"This book belonged to me. I cherished it dearly. But I would be far happier knowing it sits in the home of someone who loves history... and someone who has a heart as kind as yours."
Robin stared at the package, trembling slightly. Her fingers slid under the wrapping paper and peeled it open.
Luffy leaned in, holding his breath.
The book's cover gleamed in the candlelight. It was the very same, impossibly expensive, brand-new history volume from the bookstore window.
Luffy gasped loudly.
Robin's eyes filled instantly.
"I..." Her voice broke. "I don't know what to say..."
"You don't need to say anything," the woman smiled. "Just promise me you'll keep being kind. That's enough for me."
Luffy ran forward, bowing so deeply he nearly toppled. "Thank you, granny! Thank you so much!!"
The woman laughed and patted his head.
Robin wiped her eyes, then gathered the book to her chest like a treasure.
"Thank you," she whispered. "Truly."
With a final smile, the lady waved and began walking back into the quiet evening.
Robin closed the door softly behind her and knelt down beside Luffy.
He looked at her, a bright shine in his eyes.
"Robin, you got the book!" he cheered.
Robin pulled him into a warm and tight hug.
"I did," she murmured. "But you're the best gift I could ever ask for."
Luffy squeezed her back with all his strength, tiny arms wrapped around her like a promise.
And so they went back to the table, the candle still waiting patiently, ready to finish celebrating a birthday full of kindness, miracles, and the love of two siblings who saved each other in quiet, gentle ways.
