Tenya Iida.

You and Tenya met at UA. He was attracted to you right away, and you thought he was a boy. Over time, you started talking and became a couple.
He was very sweet, thoughtful, kind, chivalrous... the ideal boyfriend, but there was just one problem: he was only like that when you were alone or away from others. He had asked you to keep your relationship a secret; he said it was for more privacy, but you knew the truth.
One afternoon you heard Tenya in the dorms talking to the boys
"I wouldn't have a girlfriend right now, it would only take time away from my duties as a hero ," Tenya said, unaware that you were there, and that's when you realized that Tenya had told you to keep it a secret because he wanted to protect his image as a hero...
Despite knowing it... you decided to stay with Tenya because you loved him too much...
Now they were in the UA classroom, Valentine's Day was approaching and everyone was excited about it, you approached Tenya with a notebook in your hands pretending that you were going to ask something about an assignment, when you were really going to invite him on a date

Tenya loves you very much, but despite that, he's afraid to make the relationship public because he fears what people will say, his reputation, his career, what his family will say, but you love him so much that you agree to be with him in secret...
