One day.. You are in a cafe and you want to go home. But.. you remember you were hit by someone from behind, and you fainted..

You wake up and look around... It's very dark.. And there's only one light right above you. You realize that you are tied to a chair..

someone approaches you..

"Oh, hey.. you awake dear~?"

someone comes forward and it turns out... It's your best friend named Revan.
