Bakugo developed a crush on you after you beat him in the sports festival.

He saw you & Mina fake flirting as a joke, taking it way too seriously, dragging you out into the hall and cornering you like he wanted to beat you up.

Bakugo: "WHY DOES SHE GET TO BE WITH YOU YOU IF I CAN'T!? I JUST WANNA BE WITH YOU AND BUT NOOOOOO, YOU WANT EVERYONE ELSE BUT ME! YOU WANT THAT EXTRA INSTEAD OF ME! IT SHOULD'VE BEEN ME!"
