Notes:

Hi! I've been thinking about this while writting my other fic, they work as different fics (That at some point will crash together) so if you don't want to read those is ok.

The name of the series actually comes from this fic, and...yeah that.

Again, I'm doign this just for fun and as an english practice (and well, quarantine) If you see something that is grammatically incorrect please feel free to tell me, I'd really appreciate it!

Chapter 1: Good old days

Chapter Text

Another day came, he wasn’t sure how many days it had been since it happened. He always made his way to the hospital, as if he was in a trance. At first kids left him alone for a while when everyone got notice what had happened to his mom -he really didn’t knew how to feel about the fact that the teacher told the entire classroom about it without asking him first- but after a week of receiving pity stares, some of his bullies started to be mean again

‘It’s all because you’re quirk less’ ‘The quirk less is going to become also the mom less’ ‘you couldn’t do anything because you are useless’ ‘useless little Deku, who couldn’t help his mom’ ‘and he still wants to be a hero’

Thankfully Kachaan hadn’t joined them, he still remembered the good old days when they were still friends…when none of this had happened.

~~

“Hurry up Izuchan! We gotta beat them to the top!” they were playing at the monkey bars, Katsuki and him had teamed up to beat the other kids to the top, far away one could hear aunty Mitsuki screaming at them for being so high and the worried remarks of his mom. Both of them were four, both of them had grown together since their mothers were childhood friends…both of them were friends.

~~

He didn’t know what he would do if Kachaan joined the others in their taunts, because his mom liked him. She still hoped for them to be good friends, that was why he hadn’t been able to tell her about it, Kachaan had been ignoring him, like everyone else. Without really knowing how he had entered the hospital and was now inside his mom’s room, her face looked pale and he really didn’t like all the tubes and machines attached to her, he had come to hate the smell of antiseptics. This didn’t smell like home, to fresh baked cinnamon cookies, this smelled like hopelessness, a bitter reminder that he couldn’t do anything that day.

Maybe everyone was right, and he was just a little useless Deku. He could still remember her screams, her despair, her tight hug around him in a vague attempt to protect him from harm. The big explosion, the fall of debris all around them, blood, his mom going limp. He couldn’t do anything to prevent it, nothing to stop it and he had been a nuisance rather than helpful. The paramedics had had to literally torn him away from his mom, maybe those precious minutes could have prevented her from becoming like this, maybe this was all his fault, maybe she would have been better having a kid with a power full quirk, power full enough to protect her.

But him, he, he was just a DEKU

~~

“D-E-K-U that’s what it says!” Kachaan declared proudly after reading his name tag, everyone cheered because his friend was amazing for being able to read, but something wasn’t right. “D-doesn’t that mean u-useless?” Kachaan frowned, oh no, he had just gone against him, and he didn’t like that. “What did you say Izuchaan?” “N-Nothing”

~~

He stopped his train of thought there, and smacked his cheeks with force, mom would be sad if she saw him like this. He brought out the book he had been able to borrow from the hospital’s library, one about quirks and their history from a medical view, he needed something to distract himself, and the book had caught his interest. He struggled with some words, but it was interesting, and when mom finally woke up (because she was definitely waking up), he would be able to tell her about it! she always seemed happy when he told her about the books he had read. Like that one time he explained to her the physics about explosions, a book he had read when Kachaan’s quirk came in.

~~

“It says here that nitr-tro-gli…cerine? is used on dynamite!” He had been talking with Kachaan about his quirk for an hour, he had manifested it a week ago and as a good friend Izuku had gone to the library to research about it. Katsuki may had been the first to be able to read, but Izuku easily caught up to him, and in a sense, he had surpassed him, consulting at the tender age of four and a half books about physics and chemicals that were at high school level. All in order to help his best friend with his quirk.

“It’s called nitroglycerine! And, woa, do you think I’d be able to make big explosions?” The quirk so far just permitted him to make small sparks. “If you train it, I think so, you will be such a great hero Kachaan!” “You have to hurry up with yours Izuchaan! We are going to be the best hero duo!”

~~

Time passed with him reading, his homework had been done at school and the nurses just came in once to give him some food, apparently someone had arranged for him to eat at the hospital. It was just any other ‘normal day’ up until some stranger decided to step in the room. His sudden appearance startled him enough to drop the heavy book, and now the man was staring at him. Said man was tall, dark black curly hair, red eyes, pale skin (as if the man didn’t know what the sun was) and freckles, he resembled, well, him. “Who are you?” No one was supposed to be here aside from the nurses, and that man, despite wearing a lab coat, was no nurse. The question seemed to have caught the man by surprise, delaying him enough in whatever he was supposed to be doing that the head nurse of the floor appeared behind him fuming.

“I told you already sir, you need to first register at the front…oh, hi Izuku” He had picked up his book from the floor and was trying to hide behind it, the intense stare of the man scared him a little bit. “Right, sorry, I’ve just arrived from abroad and wanted to see my wife” Wife? Who’s wife? Mom? The other two in the room seemed to have forgotten about him and started to discuss about correct protocol. But that one small piece of information shocked him, if this man was his mother’s husband, was he his dad? How? (Well don’t get him wrong, he did knew where babies came from, he had read about it, thank you very much) but he hadn’t met his ‘dad’, he didn’t remembered him, his mom didn’t mentioned him, he had just assumed he had no dad. For all the eight years of his life it had only been him and his mom, what was going on?

“W-who are you?” He repeated after the head nurse had given up on trying to convince the man to follow protocols. “Oh…hi Izuku, right? I’m…I’m Midoriya Hisashi” He felt how the book fell from his grasp as he vaulted away running, nope, this was not happening, he needed to find Mr. Toshiba and tell him to take that man out of his mother’s room. Whoever that was, he was not his ‘dad’, he never had one, he didn’t need one. He only needed his mom back.
