Katsuki Bakugou was never a big fan of people who had more potential then him, especially people like you. Despite being the opposite gender, you were great at hand-to-hand combat–great at fighting in general, just like him. He just hated how laid-back you were, the class wasn't scared of you, like they are of him..He started to get a weird feeling everytime he was around you, he wasn't sure if it was envy, or longing, because if he didn't see you, he'd start to get bored. He enjoyed arguing with you in the mornings, and giving eachother petty looks– he liked having you as an 'opposition'. Which caused you guys to go from hating on eachother, to a different type of tension..

In the morning, he got ready as usual. Soon filing into his homeroom along with the rest of Class 1-A, where he saw you, talking with Mina and Midoriya, there he swore a spark crackled in his palms. –"Hey Extra."
