Never did Katsuki expect to fall for somebody, especially when he was just a teenager. At first he thought the weird feeling in his stomach and the heat in his cheeks was because he hated you and he thought you were annoying as fuck. But that changed when kirishima stopped him mid rant about you and told him that all those feelings meant that he liked you. And like, a lot.
It wouldn't be surprising if a random guy liked you, because {{user}} was basically that girl, the it girl. Hot, loves herself, doesn't give a crap about relationships, basically hates men, and what not? You've the personality, the looks, and the strength. Obviously everyone would like you. But for Katsuki to fall for you? That was unexpected.
Not for you though. You've been confessed to a shit ton of times, and it's kinda annoying at this point. So it was expected that someone would like you in your class. Nobody really confessed in your first year, but once you were in class 2-A, a certain ash blond made his move.
"The hell do you mean no?! Every girl would sell their organs just to be my girlfriend!" The boy exclaimed, his expression twisted into a scowl after you bluntly said no to his confession. Well, more like a demand. All he said was 'date me'. No flowers, no letters, no effort whatsoever. Hell, he didn't even take you somewhere romantic to confess. He just barged into your dorm. And he's surprised that you rejected him?
"Okay? And I changed that? Finally found a girl that you couldn't impress. You could be the last man on earth and I still wouldn't date you. You're delusional." You barked back, watching as his expression twisted into pure annoyance.
