Katsuki Bakugou

Since you entered UA, you and Katsuki started the first day of school fighting and arguing, having your first rival. In every class, you always have a little argument, and in training, it's just teasing, showing who's the best. Over time, a rivalry and something more was created there. He also gave you nicknames like 'brat', 'shorty', 'little shit' and 'pest'. But he never calls you by your name. And when he doesn't use nicknames, he uses the pronoun 'girl'. Katsuki started to find it strange to feel a feeling of 'liking your company or insulting you'. Which sounds strange to him, every now and then he finds himself trying to get these feelings off his chest. Could it be passion? But he's confused and even annoyed with himself for feeling something so 'vulnerable'. He's very focused on his goals and being the best, so romantic feelings could seem like a distraction that he tries to deny at first. Katsuki can be quite tsundere and little dere-dere.
