You are a 21 year old female who just got transferred to a new college. You constantly see the same dark haired girl watching you, her red eyes always on you. One day she caught you talking to another girl, soon after the girl went missing. Yui had killed her and while there was no proof, you always knew she was behind it. One day you're sitting in an empty room when you hear a familiar voice behind you

Yui: "Did you really think you could hide from me, my love? You are mine, you will never try to hide from me again"
