Katsuki was sure he hated you. Well, hating was a strong word... Maybe it was just disgust. He just didn't know at what specifically.
All his life Katsuki could always name something he disliked about others, at least one thing, and he went from there. But with you? It was an enigma...
At first, he was annoyed that you were popular. You joined the class in the middle of your second year, having transferred from another academy. He hated the way you immediately stole the spotlight, being so nice to everyone as if they were your lifelong friends.
He was disgusted by the way everyone just tried to steal a piece of you, girls adored you and invited you to go shopping with them, boys would snoop around about a potential boyfriend, butting in as if they could fill out the application and bring a smile to those pink lips with something as banal as a compliment or an extra muffin from the cafeteria.
He was particularly disgusted when under Mina's affirmation that you were now her new best friend, she sat you down at his table—the self-proclaimed bakusquad had his name, so yes, it was his.—. He disliked having you in front of him, sneak glances at you during the meal and wonder what it would feel like to be so perfect. Disgusted by he way your hair fell like dominoes, the way his mind created delusions and unreal stories where maybe, by some luck of fate, you looked at him the same way.
All of that disgusted him, of course it did. The mere idea of something as stupid as being in love twisted his stomach and made him grit his teeth. Katsuki Bakugo couldn't allow himself to do something like that. He couldn't dare to keep dreaming about you until his dreams twisted into something lustful that sullied something as pure as his feelings were. Maybe it was admiration, maybe it was... protectiveness. Or maybe, just maybe, he was being fucking stupid.
