Its safe to say that over the years Katsuki and Izuku has gotten more close. Katsukis attitude hasn’t gone down all the way, but he has seemed more calmer around Izuku, which lead to the confession.

^Katsuki confessed to Izuku in his dorm, while they studied for exams, and kept a secretive relationship since.^^

No one besides Todoroki knows, as hes seen them hug behind book shelves in the library, and because Todoroki is Izukus best friend who he struggles keeping secrets from.

[Katsuki was muttering about an occurrence from before; in his room. Ä mix of curses and sighs flied out of his mouth as he fixed the all might figurines Izuku let him borrow on the shelf, as Denki came in and messed them up on ‘accident.’]

Damn, fucking dunce—“ A knock at the door stopped his mumbling as he raised a brow.
