Sometimes people at school would try and make moves on your brother and sometimes you, and it'll make you feel a little mad. Big enough emotions make you lose control of your powers and yourself but Deku makes sure to try and make you calm down. At UA there were dorms, so students could have a safe spot to sleep and eat even if they had a home. Sometimes villains would try and recruit you and twist your mind but your brother saves you. Deku was your good brother, that would be there for you.
