Katsuki's New Sibling Life (boku no hero academia x child reader)

Valentine Special: I love you, Idiot

SLUUUURRP!

Your juice box sound as you suck all the juice out of it. Sharing a joint tables with your friends you all happily ate lunch. Each making fun and annoying the other as they spend their time at lunch before the afternoon classes.

Over in another group, you overheard them chatter giddily catching words like 'Valentines day' and 'crushes'. Now before you say anything, yes you know what Valentines is. Its a fairly celebrated event in your orphanage, where you make cards to appreciate your friends, roommates and caretakers. The caretakers would make some sort of chocolate themed treat and you either eat it or give it to your 'valentine' and maybe you can get one back in return.... Or you could just eat it yourself.

As if reading your mind Akira turned towards you and the boys and asked. "What are you guys gonna do during valentines?"

With a scoff Tora replied. "Obviously, the teachers are gonna ask us to make cards for our parents." Kōyō nodded in agreement to that making the maroon haired girl frown.

"I mean what are you, like are you guys gonna make treats?"

"Aoi, told me that's the girl's duty to do that." Tora say shrugging. "Don't forget there is still White's day." Kōyō added making the boy pout.

"I don't wanna do that! Making stuffs are a pain!"

"Hmm? Well, if you are like that then maybe I shouldn't give you any chocolates!" You smirked when your friends' heads turn snap to you. "You're making us chocolates?" Akira asked for the group.

"Well, maybe. I'll ask my mom to teach me." You chirp grining at the thought of you baking with your mom.

With a pink face Setchi pipped up about doing the same. "Huh? But its a girls thing to do that..." Tora whined earning a light hit from you. "That doesn't mean we can't appreciate our friends!" You argued making him sigh in defeat. "And you just want the treats!"

"Guilty as charged." Kōyō cut in before Tora can protest, earning a grumble from the white head. "And, besides I wouldn't want to be here when it's that day. We get a lot of chocolates anyways.."

"Oh?" You curiously looked at Akira to explain. "W-Well, like some of the middle school boys.. Tora and Kōyō are kinda popular... some of the higher grader girls would come over here and give them some along with the other girls of our grade."

"Hah!?" You exclaim in shock before looking at the two in suspiscion. "I sense bribery. There must be some sort of foul play..."

"Hey don't be salty! We didn't ask for the many chocolates anyway!"

[--]

A few days passed since that talk and it was Valentines day before you knew it.

The moment your alarm went off you were flying off the sheets and down the hall to tackle your parents in bed. "Happpy Valentines Day!!" You squealed laughing at their surprised look.

"Happy Valentines Day to you as well" Father gasp out from the force of your actions, watching your tail swing back and forth rapidly. Your mother chuckled at you two before suggestting to greet Katsuki too. They watch you dash of missing the mischevious glint in the wife's eyes. Her husband looking unsure if it was a bright idea.

Without a second to lose, you slammed the door open waking the boy up. But he couldn't process the situation fast enough, for you barreled yourself straight into the blonde's form, Effectively knocking the air out of him.

"Happy Valentines Day!!"

"....."

Katsuki was out for a little while after that.
