SIDE EFFECTS

Summary:

Phayu and Rain are insanely in love and obsessed with each other. Phayu is the leader of the mafia in Bangkok and Rain is a beautiful, bratty and chaotic Architecture student. One morning Phayu wakes up to his hand cuffed to the bed and no rain. This is a DELICIOUSLY DARK and hilariously exciting journey of their relationship and all the drabs in between providing an insight into what happened that fateful morning.

Notes:

I, like many BoNohs are not ready to let Phayu/Rain go as we welcome CirPhu into our crazy AU, so I wrote this fic as a very different and intense relationship between PR so they might look unhealthy or even toxic, they’re both yellow flags to each other but i promise no sort of abuse between them.
NB: THIS IS AN AU!!!, not even canon-divergent. completely different personalities, different settings, different drama. If you want LITA Compliant, it isnt here.
Note: Phayu is not an innocent man, he’s the leader of an organized crime syndicate, he does bad things but not to our rain AND i promise you will love him!
Also, please ignore errors as I'm sure you will find a few and I hope you love this as much as I do.

NB NB: THIS IS A WORK OF FICTION, It is meant to be lighthearted and an escape from reality, don’t confuse real life for whatever you read in this fic.

(See the end of the work for more notes.)

Chapter 1: TRIGGERS

Chapter Text

Phayu’s POV

This boy is going to be the end of me. 

You see, I’ve known that for a while now.

Hell, I’ve known that from the first time I set my eyes on him. He’s the only one powerful enough to take me out of this world and will I gladly let him , do it? I never deny him anything so yes. 

I consider myself a very powerful and principled man, level headed, with the sharpest acuity a man can have. Afterall, that was how I built my empire 10 years ago from the ground up. 

The mafia or organized crime syndicates all over the world have this distasteful reputation of being ‘gangsters’ but not me. 

I am as polished, educated and suave as I can be, I have patience that can rival that of saints, more self-control, more calm and ease to my being than most ordinary men.

But over the past year, everything I thought I was has been shaken to the very core. 

I have been tested at every turn; everything I thought I had-had been rendered useless by chaos itself in the form of a 5 '7 little blonde-haired, grey eyed demon specially sent to me by the devil himself.  

On second thought, maybe God sent him to me because the first time I set my eyes on him, I bragged to my men.

To God, I laughed.

How careless could He have been for me to set eyes on one of his Angels because I was a selfish man. 

I had everything else but an angel, and I was going to keep him for myself but maybe it was intentional after all. I have broken enough commandments; I have killed, coveted and lived lavishly to rival monarchies, lusted, stolen, cheated enough to satisfy the devil so I am sure God sent him to me as a punishment instead.

That is the only logical reason why at 1am when I should be asleep, with him in my arms, I am shooting my men one after the other for not knowing where he is.




The morning of that unfateful day…

Something is not right. I can sense it immediately that my boy is not asleep beside me. 

Okay, Phayu don’t panic, he could have gone to the bathroom ... but with the way I feel, I am most certain he is not in the bathroom.  

He could have gone downstairs to the kitchen to get some water but to avoid not waking up without him is why I always make sure the fridge in the room is stocked with everything he could ever need as long as we are both in the room together.  

All the thoughts in my head ground to a halt when I try sitting up and my hand is in a weird position. 

Okaaaay this is weird, I am cuffed to the bed? We did not have sex yesterday and even if we did, I wouldn’t be the one cuffed and certainly not for this long and it’s just my left arm? 

What the hell is going on and where in the loving fuck is Rain?

 

Rain! Baby are you in here? Rain baby Come on stop playing, I have to get to work" I call out into the empty room.

 

I know deep in my guts I wasn’t going to get an answer because if he was around me, I would feel him. He’s woven into my soul like that, he’s a part of me that I can’t live without, I refuse to live without. 

Dread crawls up my spine and I can feel the goosebumps prickling on my skin.

Is he okay? Was he taken somehow even with the hundreds of guards surrounding the property? Maybe he’s in the garden with P’Vine? 

So many questions. 

I can already feel the onset of a migraine. 

Where the fuck is he?!

“Anyone out there???”  

No response…

I test the cuffs on the bedframe and it just rubs harshly against my skin. I can see the red marks that begin to form around my wrist.

Fuck, I‘m so not in the mood for this.

 

Baby stop playing, I am going to count down from 3, you know what happens when I get to zero”

 

Once again, silence.My baby is everything but one of the things he certainly is isn’t subtle.

I would have heard his breathing hitch or tiny shuffle of his feet because he physically can’t be quiet for shit. 

He claims he hates it when I count down, but I know he secretly loves it.

He loves the chase, loves his punishment and he loves his rewards when he obeys even more.

The returning silence except for the lull of the air conditioner just confirms it. Rain is not in this room, and it is becoming a problem.

I try twisting my body to feel out the bottom of the bed frame for either my knife or the gun stashed there but both are surprisingly missing. 

Hm, interesting. 

The only person that knows exactly where it is asides myself is conveniently missing with my weapons. I try searching the bed with my one free arm to find something, anything to free myself and my fingers land on a small note. 

Don’t be mad phi!

I’ll be back soon, I promise!

Well, maybe a little bit later but you can get a lot of work done and you don’t have to give me so much attention!

When you’re thinking of all the ways to punish me, remember you love me so much and I’m the brightest sun in your world and you love my smile and my bunny teeth and my lips and my doe eyes and my hair and my waist and my…”

 

Reading all the things I’ve told him over and over that I loved about him, it’s obvious all the rambling that’s always going on in his head is what he tried to put down on paper and I’m surprised he didn’t get a bigger note. 

Problem now is, he wrote down everything except where the keys are and where his little ass went to.

For the first time since I woke up I have a big wide smile on my face.

As I run my tongue on my top teeth, I shake my head and sigh.

There goes the normal, less stressful day I was hoping to have. 

I should have expected this, these are the kind of things I foresee in my business and make plans for, but Rain is always an anomaly for me. 

He’s been quiet lately, too quiet. 

My boy has ADHD.

If he’s not bouncing all over the walls from excess energy, he’s burnt-out; needing comfort from only me. 

There’s no in-between, at least until lately. 

He’s been good, suspiciously so, even obeying me with a little bit of pouts here and there but he’s been good…too good. 

And I should have known. My baby is a brat, a spoiled brat, but he’s not a calm or quiet spoiled brat either, so with this turn of events, I should have seen it coming. 

Okay Rainy, you wanna play? Let’s play.

I can feel myself getting hard. He knows I love to hunt and he’s the perfect prey.

What, does he think he’s getting away from me?

Big mistake. 

I obviously have not shown him enough that there’s nowhere on this earth I won’t go to find him. 

So, if he wants to run, he’d better run as far as his little legs can take him. 

Daddy’s coming .

 

I try to search the bedside table for at least a pin or anything that I can use to free myself, because God forbid the most feared man in the whole of Bangkok can’t get out of some flimsy cuffs!

But my search is fruitless because of, once again, Rain. 

I put all sharp objects away because of my clumsy-as-fuck boy. 

He‘s a walking hazard; if he doesn’t harm himself, he can harm me. 

I have nursed enough wounds from his architecture projects. Sometimes I wonder why he’s studying that subject at all.

Sigh, he really thought about everything. I am not sure if I should be proud or think of all the ways to turn his ass red so he can’t sit for a week. 

When he completes his school projects it‘s always like he’s at war, but he can do all this without help? Oh, he‘s so getting it when I lay my hands on him.



My men know I have a strict schedule I always kept to until who came and disrupted the order in my life? Rain.  

If they have not seen me down for breakfast, they will come check.

But then, ever since he moved in- there are days I have lazy mornings with my baby, especially when I wake up and he’s still asleep, looking all angelic and innocent.

I get this strong urge to touch him and kiss him lightly, something about the way he pouts so cutely with his lush pink lips and scrunches up his nose just gets me going. 

It takes a lot of tries to wake him up fully and it usually ends with lots of promises and compromises. 

The days I have the urge to take him first thing in the morning, to connect with him before I connect with the world. I have no idea how I lived without him before.

I feel a sharp pain in my chest - it could be a phantom pain my mind created because my boy isn’t here - but it feels as real and physical as it can get, and I cannot have that. 

I need my boy, and I need him now.

 

I can hear a knock on my door interrupting my thoughts- Sigh, about time already.

Open!” I called out.

I see the guard standing at the threshold of the door and even from here I can see the shock and confusion play out on his face. 

“Come in ”, I tell him

He hesitates and looks unsure, “ Sir…

It’s fine, Rain isn’t here.

It makes sense that he’s hesitating, because Rain had once threatened to cut off the balls of a guard when he tried to come into our room. 

If you think I am possessive, my boy is twice as possessive. 

There are three places my guards aren’t allowed to be in; the glasshouse where Rain grows all his pretty flowers with P’Vine; our housekeeper, his classrooms and our bedroom.  

 

I look at the guard and see the skeptic loom in his face, i cannot believe my guard is more scared of Rain than me!

I pay his fucking salary, I have his life in my hands and he’s afraid of a hypothetical threat on his balls? 

Granted my baby can be quite scary when he wants to be, but there’s only one evil here right now and it is not in the mood to play around.

As I try to sit up I can feel hurtful tingles running down my forearm.

I don’t know how long I have been cuffed for and it is beginning to hurt and I can also feel my bladder full, I have not relieved myself this morning. 

I am so done with this shit.

I don’t yell, I have no reason to. 

My calm voice and face do all the talking for me but right now, if this idiot doesn‘t move his ass I‘m going to yell down the entire house and the other guards will spray him with enough bullets before he even has a chance to look innocent.

 

Taking a deep breath I look at him and tell him calmly:

As you can see, rain is not here. I don’t need him to harm you for me, personally i am even insulted that you think so. But if you do not get your ass in here in two seconds and find a way out of these cuffs, Rain and your balls will be the least of your worries.

He quickly rushes inside and makes a motion for the key

“k …k…key boss?

Uh? This. Stupid. Fuck.  Are these the men in my employ? 

oh let me just check……do I look like I have the fucking key and  just want to lay in bed all day??!!!?

I try to take a deep breath again. 

I usually don’t cuss, except during sex with Rain or when I‘m  pissed off and ready to shoot somebody and this guy might just be my first body this morning.

I don’t know what look he saw on my face but it must have been deadly enough for him to spring into action.

The genius tries breaking off the wood the cuff is attached to.

God, I can feel my temple pounding, I pinch the bridge of my nose in exasperation and sighed again. I seem to be doing that alot this morning.

I sit up as much as my hung arm allows me and face him, “ You idiot, how do you want to explain the broken bed frame to Rain without telling him you were in the room?! Besides, do you think I spent all that money on this kind of wood for me to watch you break it ?” I gritted out.

I can tell he is getting more nervous because now he’s scared of Rain coming back to meet him in the room and of me because I was already gritting my teeth and wincing from the uncomfortable painful position my arm was stuck in.

And he had no solution, which was one of the many reasons I take out my men.

If you have no solution, I have no use for you, end. 

Luckily for him I do take pity on him because he’s essentially just caught in this game Rain decided to play and he’s the unfortunate one that had to knock on the bedroom door this morning.

Check Rain‘s bedside drawer, the key might be in there

I refuse to believe Rain will leave me cuffed up till whenever he gets back, but a small part of me also believes he could have just forgotten to leave the key.

As the guard rushes over and searches the drawer he takes a second before he stands up and shows it to me.

I think I found it, Boss! ” he yells. The idiot actually looks proud of himself.

Well congratulations, would you like to use it now or do you want a fucking parade?” I answer .

God I‘m pissed. 

I just wanted to have a good morning, one where I wake up with my boy, maybe wet my cock a little, have breakfast with him and go to my office and conduct my business. 

Instead, I’m cuffed to the bed, butt naked under the duvet with a full bladder and without my boy.

A lot of people are going to die today, and I might just start with this bumbling idiot beside me. 

As he unlocks the cuffs, I gingerly hold my arm and massage life into it, gritting my teeth and trying to swallow the pain.

I can’t show fear, and I can’t show I’m in too much pain. That is literally Mafia 101. 

Go and find Rain. ” 

Yes Sir! ” He quickly rushes out.

I don’t blame him, i’m cranky as fuck and i would not want to be around me too either.

As I step off the bed carefully with my still aching arm, I look at the time on my bedside clock.

8:37am the figures glare in red, mocking me. 

I usually wake up by 5 and work out but there are days I go to bed exhausted but I’m usually awake by at least 6:30.

So that means I have been awake for up to two hours and Rain has been out of bed longer than that.

He must be very committed to whatever this is because I can’t even get him out of bed by 8:00 and that’s on days he has early morning classes.

I take the band on the bedside table and tie my hair into a bun; I have been letting it down in bed since rain told me he loves seeing and feeling my long hair whenever we’re in bed together.

I pick up my sweatpants from the armchair and go to the bathroom to finally relieve myself. 

Turning around to the vanity to brush my teeth, I can see all the chaos my boy left behind. No matter how much I scold him and make him pick up after himself, he never does. 

He has a shit ton of skin care stuff and makeup and hair products laying around and I can't even keep up with half of it. 

Once I asked him why he needed so much and he looked at me like I was the weird one and said with the straightest face:

Phi, you always say you love my skin and that it‘s so soft. I am so beautiful and all that, well this is what makes all that”

“Yeah, well, I would still love you without all of that you know, just saying”

“Well, I love all this, so if you love me, you will let me have them too!”

I had no comeback to that, just kissed his neck and gave him a bank card for his skincare and make-up at Sephora; his favorite store. 

I even let him do some skincare on my face when I saw how happy he is when he gets to pamper me.  Whatever my boy wants, my boy gets. 

And some might say I spoil him too much.

But seriously, if I don’t, who will?

I can feel that ache in my chest again.

I miss him. I miss him so much it hurts, and this is why I can never be apart from him.

A few hours of not knowing where he is and I already feel this way. 

I have cameras in his classroom and at home, I can watch him when he’s not around me. Psychologists might attribute the ‘stalking’ to my need for control-it is not stalking if he knows. 

Now, I can't see him, I can't feel him, I can't…. I don’t think he knows how much power he has over me. 

I can feel my fingers starting to tremble and I grab the porcelain bowl of the vanity. 

I take a deep breath and count down in my head, willing my body to relax. 

I know this is just his game and I try as much as possible to indulge him, but we don’t do this; we don’t disappear without knowing where the other is. 

I brush my teeth and splash cold water on my face. I walk out of the bathroom to look to his side of the bed….

His charger is still connected to the wall, his portable play station is on his bedside table and his hair band as well. His pillow still has the indent his head made during the night.  

I know we went to bed together yesterday; I wouldn’t have been able to sleep if we didn’t and I try to remember if he did or said anything out of the ordinary, but I was too exhausted to really do or think much. 

I look at the time on the clock again: 8:52 am.

Enough time has passed, the guards should have had him here by now or at least informed me on where he was. 

I grab my phone and reply to a couple of urgent mails.

A knock on the door shifts my attention and I tell whoever it is to open.

I didn’t tell whoever it was to come in, I won’t have any more men in here, my baby does not like it and one for the day is enough. 

The same guard from before stands in front of our bedroom.

I look up at him and behind him, no Rain.

Where is he? ” I queried.

errmmm boss… we can’t… umm ” he swallows nervously.

I’m sure the confusion is evident on my face. 

I have hundreds of guards so I obviously cannot remember all their faces, but he’s in my house, so Saifah, my twin brother and head of security thinks he’s good enough to be around me.

Are you new here ?“

No Boss. ” 

“How long have you worked for me?” 

“Two years in training and one year active duty Boss.”

“You must know I shoot men for even wasting my time in my business and this is about MY boy. So if you want to keep breathing answer me and answer me fast, where the fuck is Rain?”

He quickly rushes out “We don’t know Sir. I asked his guards and they said he’s supposed to come down with you for breakfast. They‘ve not seen him too Boss, we checked everywhere including the green house and the garden, P’Vine also hasn‘t seen him. We have his class schedule and he doesn’t have any classes today and no exams coming up, so he’s not there reading either. We tried to track his phone bb..bbut”

He swallows again.

  1. Am. Losing. My. Patience.

He must have seen it on my face because he quickly rushes out again:

“The phone is still in the house Sir, upstairs here to be specific!”

I frown, His phone is here?  But I haven‘t seen it. 

I leave the babbling idiot at the door and go to check his bedside table again, rummaging through it all but no phone. 

I am about to turn and knock the idiot on his ass because he clearly does not know what he’s saying, when I see something black and shiny by the foot of the bed.

 

I kneel and there it is: Rain‘s phone. 

He knows I put a tracker on his phone to know where he is, he also claims I am a controlling asshole but let’s face it: I am the mafia.

I have enemies, I love him. 

Two plus two equals four. So, for him to leave it, he’s more serious than I thought. 

I feel a shudder run through my body.

Rain, Rain, Rain, what are you doing baby boy? 

There are a lot of people that would want to get their hands on him right now, he’s without protection and his phone so he cannot even contact me if he needs me.

Then I remember the diamond necklace I got for him for our anniversary. I put a tracker in that as well, but I never told him. 

This tracker is also waterproof so I told him he didn’t need to ever take it off to bathe or to swim, call it a two-factor authentication if you want, but I leave nothing to chance knowing my boy is a handful, forgetting or losing his phone and all that. 

I face the guard at my door who’s still looking at me with wide eyes. This guy is useless and It is beginning to piss me off.

Get Saifah here right now!

I pull up my phone and call Prapai, my best friend and business partner. He also happens to be dating Rain‘s best friend, Sky.

Ring ring ring

C’mon Pai pick up

And then he picks up.

I can deduce that he’s very much still in bed, but the question is, with Sky or without him. If Pai’s in bed with Sky then…….

Ai Phayu, I am not sharing my rare lazy morning in bed with Sky with you, I’ll see you at the office….”

“Pai don’t you fucking dare hang up, Rain is missing!”

He knows I never curse, and I can hear the sheets ruffling in the background, his voice sounding clearer and alert now.

“Sorry I had to get in the bathroom, Sky is still in bed. What do you mean Rain is missing?” he whispers.

“Did Sky at any point leave the bed this morning?”

“Ay no we were having too much fun except it was with my imagination and yes he was very much present. Have you called his phone?”

“He left his phone here Pai, did Sky tell you anything? if he had a Plan or if he was mad at me or something?”

“No not at all, Sky‘s spending the day with me, we were going to come to your office together later today, what happened? Didn’t you sleep at home?”

“Exactly Pai! I went to bed with him and I woke up fucking cuffed to the bed, no Rain in sight and he left his phone here”

“WAIT WHAT?! CUFFED? Did you guys fight? You know Rain can be a baby when he’s sulking”

“No, we didn’t, at least not that I remember! He just left a note for me not to get mad and that he will see me later.”

“That‘s crazy…look I know you’re obsessed with him and all, but this is Rain. If it is not architecture he doesn’t have much ideas flowing in that chaotic brain of his except just to mess with you and I’m sure you can figure out where he is.”

“Shut up Pai, I pulled up Saifah to track the bug in his necklace, is Sky wearing his?”

We bought the necklace together for our boyfriends, the difference is Sky knows about the bug in his necklace and I had to threaten him not to tell Rain (Pai was NOT happy about that) because everybody knows Rain is clumsy and forgetful, it‘s more for his own protection than anything else. 

And I told Sky he knows about the bug on his phone, so it’s not like I’m breaking so many boundaries. 

Besides, he’s mine. He has no boundaries from me, I made sure of that.

I made sure Saifah is the only one that has the software that could track the bug, I could too but I will need heavy hardware and I don’t have access to that right now,

Where is Saifah by the way?

“Yeah, my Sky is wearing his, he loves me too much to try to give me a heart attack unlike your boy” he muses

I ignore the subtle dig and roll my eyes.

“Anyways I’ll call you with any other update, I did not plan for this today atall!”

Pai chuckles and replies : “the almighty Phayu, lord and controller of everything…It‘s crazy how this one boy is completely out of your control, I mean who else can cuff you to  the bed successfully? Did he drug you? Or is he that good in bed that he wore you out?”

“Bye Pai!”

I hang up and rub my face and pull out the hairband and retie my hair. Rain says I do it when I am in a mood and oh I’m in quite a mood alright?

Now that I think about it, I don’t feel drugged.

I’ve made it a habit to feed my body some drugs especially sedatives in little quantities over the years to build a resistance and to distinguish when i am being drugged because of my line of business, so I know i was not drugged and if i was, it has to be a heavy dose and i’m sure to have felt it as soon as i woke up so the only explanation is i was dead-exhausted and pretty out of it for him to have successfully done this to me. 

We are going to have words when I get my hands on him.

Not long after, I hear Saifah at the door.

“Yu, open up”

I go to the door and open it.

“Fah where’s Rain?”

“I pulled up the tracker, but it says it's offline,” he answers.

“Offline? What do you mean offline? You said it can work in the rain or sun!!!” I basically yell out.

“Well yes, it‘s supposed to but for some reason I cannot get any signal from it”

Fuck this shit. 

Fear like I have never known before drops right to the base of my stomach like a heavy ball.

I feel like I've been hit by a sledgehammer and stagger back into the room and run my hand through my hair and grab it.

He eyes me suspiciously and asks “Yu, I swear I'm lying if I say this isn’t confusing. How did you go to bed with rain and wake up cuffed in the morning without Rain?” he stressed.

I turn back to my brother, “Saifah I am not in the mood, do something. Find Rain for me!”.

He can sense the distress in my voice and on my face and can easily deduce this is way more serious than he thought as his face softens.

“Yu I am trying, come see for yourself?”

I‘m just noticing now that Saifah also did not enter the bedroom because of my boy’s golden rule.

He’s not here and he’s still holding grown men by the balls. 

I nod, “Give me a minute, let me grab a shirt.“

Almost 24 hours later, 6 dead men; all of them Rain‘s guards (starting with the bumbling idiot at my door this morning) and there is still no sign of Rain.

Where are you baby
