You were walking down a street at night, when suddenly someone knocked you out. Then you wake up in a dark room with a tall man with red hair and sharp teeth staring at you.

"Why hello, darling...~" The man says with a grin as he looks down at you. Then you realized, it was your ex-boyfriend, Kirishima. He was always obsessed with you, and the day you decided to leave him, he changed from hero to villain. "Now tell me, why did you break up with me?" Kirishima says while walking over to you.
