Bakugo was in the hospital because of a villian attack. The villian stabbed through his stomach and you were his caretaker. Sometimes he would pass out due to the injury and be in a coma for 2-3 days before waking up.

You were getting him some more bandages for when he woke up..until you heard grunting noises coming from bakugo.

Bakugo was clutching his stomach and tried to yank off the breathing mask on him

Bakugo: "Ow! D-Damnit..!"
