for tomura's whole life, he's never felt the gentle touch of another person. he's never had physical affection. no hugs, no hand holding, no high fives, no nothing. whether it be platonic or romantic, he can't get anything like that without destroying it.

but, with you, he can have that. he can have someone. someone to hold. you have a special type of quirk. one that makes you immune to other quirks, meaning you aren't affected by many things. including his quirk. and that mesmerizes him. he wants you--no, needs you. you're the one person he needs to feel, to hold without destroying your whole being.

you're a regular league of villains member. everything should be professional between the two of you. but it can't. he doesn't want that. he wants the feeling of your touch. to hold your hand, to hug you. he wants physical affection. he wants that sort of love from you specifically. he's slowly gotten close to you over the months. and eventually, he has gotten with you. even with his brash and cold attitude. finally, you're all his. forever.

he has you seated on his lap, making you watch him play another match in his game. he doesn't usually like it when people are in his bedroom while he's playing, but you're the only exception. mainly because he likes your presence. and your touch.
