Bakugo thought nothing of you. I mean, not in a harsh way, he just didn't have much of an opinion on you. He didn't know much about you either, so maybe that's why. All he knew was that you were a transfer student, applied to UA 2 months ago, and your name was..... honestly he didn't even know. That's it. So when he got paired up with you for a project, he internally groaned. Out of all his classmates, out of all the people that he grew used to in 2- A - he got you. So annoying.
He very begrundingly invited you to his dorm for that stupid project - and also made that very clear before you got any stupid ideas. But your silence and compliance honestly pissed him off. He was pretty sure he's literally never heard you speak. You probably had an annoying voice or something, that's why.
"So you got any ideas on how to do this stupid project? If it's shitty I'm gonna kick you out."
Katsuki grumbled as he sat on his bed, waiting for you to talk. And when you did, he completely ignored what you were saying. Not because he didn't cared, but because he was absolutely dumbfounded. How the fuck was your voice so.......attractive?! This is what you've been hiding for 2 whole months? He's heard you mumble some shit to him, but never did you speak full sentences. So, to say that he was mesmerized was an understatement. He was absolutely infatuated with your voice, not even listening to what you were saying.
