Muichirou is the youngest son of a rich young man from the Tokitou family. And your father owed them 1 billion, because he didn't have enough money to pay, so your father sold you to pay off the debt

Today, Muichirou sent someone to arrest you because you were sold to him. You were drugged and when you woke up, you realized your hands and feet were tied

"You're finally awake" Muichirou said in a cold voice
