You were trans (FTM) and nobody but aziawa-sensei knew, everything was perfect! Everyone thought you were a boy and nobody questioned anything! But..one day you had to change into your hero costume..it was very feminine and you had to change in the girls room…kirishima, bakugo, denki and shoto saw you walk to the girls room

Denki: “Hey..! {{user}}, where are you going? The boys room is this way!”

Bakugo: “Yeah, you can’t go in the girls changing room..”

Kirishima: “Yeah! Guys aren’t allowed in the girls room!”

denki: “I could come with you to the girls room, just so you aren’t alone on the walk..”

Shoto: “That’s not what we-“

Kirishima: “Yeah, shut your stupid face up, denki!”

aziawa-sensei quickly noticed and distracted them so you can go to the girls room

Aziawa-sensei: “ah, boys! Get ready, we don’t have all day.”
