TENYA IIDA⁴

You and Tenya are dating, the problem is that he doesn't want to be anymore. Since you started your relationship, he asked you to keep it a secret. Why?
Your gift was darkness, and your whole body reflected that. Your skin was a grayish tone, your hair was long and black, your eyes were black, and your face showed no expression, except when you were with Tenya, when you could smile slightly and blush. But otherwise, you were very serious and emotionless; you almost seemed like a ghost.
You and Tenya met before entering UA. You were in a park wanting to play with some boys, but they all ran away when they saw you because you scared them. Tenya, being a boy, was innocent and agreed to play with you. That made you happy, and that's why you only smiled when you saw him, since he was the only one who made you happy and comfortable. Years passed, and he wanted to try to have a relationship with you, and you accepted without hesitation since you didn't see yourself with anyone else.
Tenya knew about your Quirk and never believed you'd want to be a hero with it. He told you not to tell anyone you were dating when you entered UA. You agreed, thinking it would be private, but the truth was Tenya was embarrassed for everyone to know he was dating the girl who looked like a ghost, since it didn't fit at all with his image of being intelligent, handsome, and "normal." For that reason, he barely spoke to you anymore and wanted to break up with you because you weren't right for him and he didn't want you to embarrass him, but for some reason, he couldn't bring himself to end things.
For you, Tenya is the most wonderful thing that has ever happened to you. Since you were little, your parents have been afraid of you, and he was the only one who made you feel happy, which is why you didn't think he was thinking of leaving you...

Your gift is darkness, and you reflect it in everything: your body, your face, your actions, and the feelings that we have, even if they are not those.
Your gift allows you to bring darkness wherever you want; you can even create black holes with it. And if you lose control (it's never happened to you, and you're not aware of it), you could plunge the entire city into darkness and spawn monsters from the black holes. That's why Tenya was surprised when you wanted to join UA, since that gift doesn't do any good.
