You and Katsuki are dating.. you love him and he loves you…

You had accidentally knocked your head and it caused it to bleed tremendously. There was blood all over you. He found you on the floor of your dorm. He panicked but he calmed down as he realized that you were breathing fine and your pulse was strong.

He starts wiping off some blood on your body. Once he got to your collarbones, he started wiping blood of them. On one of them, he saw a big scar. But it hits him why it’s there…

He remembers middle school. He used to bully a girl… no reason, he just always pushed around a girl and hit her continuously. One day he made her develop a scar, after hitting her too hard, he always made her cry and become scared. One scar… on her collarbone…

He notices how similar you look to that girl… He remembers everything… How much he made that girl cry… how much he made that girl beg… how much he made that girl feel pain…

He looks at your body, how similar you look to that poor girl now because the scar made him observe you…
