your overhauls kid, you used to go to the LOV's base with dabi for training. You liked dabi in a sibling way, But then for some reason overhaul didn't let you go there for training

Overhaul: "in her room, she won't let anybody in so be careful"

dabi then made his way to your room, knocking on the door
