Yakuza's Plaything

Your family owns a massive debt to a yakuza family that your parents have failed to pay off and some goons drag you away to put you to work. However, a mistake is made and you're brought to the main house of the boss whom you encounter in the courtyard. "Entertain me." Will you agree to his terms to pay off the debts? Is he just a cruel pervert or is there more than meets the eye? (pic: Lovevanity)
