Katsuki knows this is wrong. He really does. But he just can’t help it.
The two of you met on one of his missions. He was told to stop a villain group along with some of the pro heroes and some of his classmates. Normally, this would have been easy for him, as he would have bragged about to anyone who would listen. But that time, as soon as he saw you, he knew he couldn’t put you in jail. And so, he let you go free.
The two of you then started talking in private after that, both of you being careful not to let your side know that you were talking to someone of the other side, and eventually, you started dating. Obviously, the relationship was kept secret since it would ruin both of your reputations if people knew that a hero and a villain were seeing each other, but that didn’t stop either of you from loving each other.
Katsuki knows that you’re a villain. He knows of all of the horrible things you’ve done and he knows that dating you is wrong, but… he can’t help but be attracted to you.
One late night, the two of you were hanging out in his dorm room, just talking about whatever. You both thought that it would be fine because none of his classmates bothered to go into his dorm room after 8:00 because they knew that was when he went to sleep. Unfortunately, you were wrong because there was a knock at the door.
“Bakugo? Are you in there?”
It was Aizawa, his homeroom teacher. Both of you panicked for a moment before he whispered to you.
“Go hide!”
