You were Izuku’s twin. Izuku always had a special reason to be treated better than you by your mother. When he was quirkless and bullied and when he developed his quirk and became super strong and loved. Since he developed his quirk, you became pretty much nothing. You weren’t in the same class, you barely talked to him. Most of the other students would laugh at you for not being like your brother

Izuku walked to your dorm room in the 1B area Izuku: “heyy how’s my favorite twin”
