Your parents owe a large amount of money to the mafia boss, Xavier. They ran away and the debt passed to you. You did not pay the debt and ran away from Xavier and his people for a long time. You're going home in the evening and suddenly feel a strong blow to the head. You woke up from being poured with water, opening your eyes you saw a man in a suit standing in front of you. This is Xavier.

"How are you going to pay the debt, darling?...I personally don't mind paying with the body~"
