You and Katsuki have been growing up together ever since you guys were kids back then, Katsuki only allows you and Deku to call him his nickname 'Kacchan', you thought that it was really cute so you nodded in agreement but you never told him that it was a really cute nickname because you were too shy.

And a little bit you didn't know is that Katsuki secretly likes you and has a big-crush on you without even not knowing what it means because both of you guys were kids and it was all because of how kind, shy and really cute! Then that's when until you both grew up in middle school. You guys are supposed to be inseparable from each other!

but guess what? The universe has other plans, or should I say a nightmare universe.

You both got separated from each other in middle school and you didn't even have the chance to send letters, texting or calling each other anymore since you both started to forget each other..

Until that's when your mother and a lot of siblings—because your father wasn't always there for you ever since you're a newborn and you never saw his face because he abandoned y'all cause he thought that you're only a disaster and a curse because of your weird glowing patterns which is the cause if you lost control of your 'cursed' quirk—Your mother and Siblings explained to you that a boy named Katsuki Bakugo was your best friend because your curiosity got the best of you when you found a picture since you were a kid with a blonde, explosive and tsundere kid beside you in your mother's phone.

That's when you thought that you were going to call him 'Brother' which is his nickname because you thought that it was his nickname. Which is NOT.

Then some days or maybe months pass and you turn into a teenager and you're in UA now because you trained and focused on every lesson to get inside UA school because you thought that it was really cool and it inspired you to become a hero despite still being slightly shy now!

That's when your first class is 1-A which is Katsuki's class as well!

Was it a coincidence, faith? Or Destiny?

You were right outside of the classroom door waiting for Aizawa-sensei to announce that there'll be a new student who is a girl.

And you also don't know that Katsuki is really famous now which he kinda half-hates because you know why?

It's because of his annoying three fangirls—Katsuta Mikoto, the Pick-me manipulation leader of the Katsuki fangirls, Himura Saki and Sakurai Miwa are her members, they've always been following him for the past two weeks now, no matter what he does to make them leave him alone, snap, annoyed, angry at them, they still won't leave him alone like they're a parasite that already clung to him.

And he secretly likes his friends even though he's to tsundere about it!
