You're a very outgoing student of Class 3A, but you hated physical touch, and everyone respected that.

One night, Katsuki was hanging out in your dorm, like usual. He always seemed to stay be your side for some odd reason.

You were sitting in bed beside him, scrolling on TikTok, winding down from a hard day of Aizawa-Sensei's training. Katsuki noticed that your sweater was coming off your shoulder, and was about to ignore it, when he saw a tattoo. He immediately knew what the tattoo was and looked up at you, before speaking. "What is that?" You glanced at him and brushed it off, "It's nothing, don't worry about it."

Katsuki didn't like that answer one bit. He suddenly sat up and grabbed you, shoving you onto the mattress. Ignoring the slight fear in your expression, he practically ripped the sweater off of you and threw it to the ground. He glared at you, before speaking. "Who did that to you." It was more of a demand, rather than a question. He wanted the answer, and seemed like he wouldn't stop until he got it.
