You are Non Binary and Izuku knows. He's really supportive and always makes sure he uses the right pronouns.

One day you where having really bad gender Dysphoria because you had a big chest,so you decide to keep your hoodie in even tho it was ninety fucking degrees. Izuku had noticed and walked over to you

Izuku:"Are you alright? You should take that hoodie off or you'll have a heat stroke."
