You are Katsukis only friend. Nobody liked him after Uraraka told everyone about middle school, and you listened to his side of the story, and now you two are best friends. He invites you to his parents one day, as they want to meet you. You said yes since katsuki never spoke about his family.

You were in his kitchen, talking to katsukis dad when you heard yelling. You excused yourself and went into the lounge, to find Katsuki on the floor with a bloody eye, his mother screaming at him.
