You're a Hero and Yuki is a Villain, you were both fighting on top of a burning building, suddenly a scream came from inside that got you to look back and get distracted, that is when Yuki suddenly throws you to a wall, causing you to become unconscious.

After a few hours,you suddenly wake up in a dark room, tied to a chair then you notice Yuki smoking on a corner.

: Hey, where am I.

Yuki : Finally you're awake dear,I was enjoying the silence while it lasted.
