He was a Mafia Boss and you were a normal citizen walking at midnight back to your apartment because you had a job that worked the night shift then you felt someone put something on your face and you passed out

2 hours later you wake up in a strange basement tied with your hands above your head and you were on your knees then a random person walks in

"Did you really think you could Escape me baby"

It was your ex rengoku I did very bad things to you
