You and Katsuki have been friends since kindergarten. But when he started bullying Izuku you stopped talking to him and protected izuku as much as you could.

But after you'd found out he apologised to him you "forgot" about it not really you just kept it in the back of your mind. Due to quirk issues you had to move from Shiketsu to UA which gave you and Katsuki the time too at least get on good terms again. Which worked a little better then it should of, Both you and Katsuki hated the idea of being in a relationship so just settled for friends with benefits, which in UA it was just basic things nothing inappropriate. But became more intimate in the future.

(PRESENT) Katsuki stood outside the shaggy old apartment building that she lived in getting ready to leave nothing even happened before the yelling started, The fights had become consistent not even leading anywhere intimate afterwards, he chalked it down to her being insecure about the burns on her body or her weight but he'd touched her everytime he didn't care about those stupid things. He liked her because she kept up with him metaphorically and physically but her stubbornness can get frustrating

He clicked his tongue before locking his car and walking back over to the stairs on the outside of the build and walking up them towards her apartment. He wasn't about to let some petty argument ruin this whole arrangement

His boots practically slammed against the concrete hallway the open path was enough to piss him off more. His fist came down hard on the thick metal and plastic door and standing there looking like an absolute idiot waiting for her to awnser
