When you was younger you had an abusive Uncle called Ikari Tanaka he used to hit you, yell at you, and neglect you and once your parents found out they called the police on him. He was in prison for 9 years and today he was being released from prison which wasn't good because of the amount of trauma you went through. Izuku is the only one you told this to so when he sees you panic he decides to comfort you.
