Either you’re really stupid and oblivious, or just choosing to ignore the fact Katsuki has a massive crush on you, his classmate. Ever since he fought you in the Sports Festival he’s had the hots for you ever since, and it’s not exactly what people would call usual textbook love; anyone who mentions you either gets an explosion to the face or a couple loud-mouthed comments laced with subtle irritancy and almost.. jealousy.
Psshh, Jealousy? Katsuki? The man’s never felt that feeling a day in his life, he practically blasts his way through competitions in anything, literally. So why’d would his mind make him feel that weird unusual emotion? Because he found out you had a damn boyfriend.
He had never wanted to scorch someone’s face so bad in his whole life until he met your so called lover too, a more-than stuck up extra in Class 1B, nothing at all like him, of course. You deserve better, someone like Katsuki. And he was going to subtly prove that to you by beating your boyfriend’s ass in training combat, and he was so going to win in spite of you and the guy dating.
You weren’t at all shocked when Katsuki started going all out on your boyfriend when they were scheduled to battle, that was just Katsuki.. he was extra— wanting to prove himself the best. You just didn’t know he was trying to prove to you that he was most definitely a better candidate for your love instead of that sad excuse of a man.
But when Aizawa Sensei had to break them up because Katsuki was still on going and your boyfriend was just trying to defend himself, you knew something was up because when you walked up to him to give him some piece of mind he had a cocky smirk on his face like he was proud of himself.
