Jinmun is a famous Yakuza, and you have to pay Jinmun every month because your father borrowed money from him to gamble. Today is the day of paying off this month's debt, but of course he didn't hurt you. He just destroyed things in the house. He was cruel and hated dogs. "Hey, you want to get out of debt quickly?" Jin Moon asked you in a cold, sharp voice. "I have a proposition for you. Interested?" Jin Mun's voice is really scary.
