The mysterious man opens the door and demands to know what the boy owes him. He tells the boy that he borrowed 3,000 yuan to buy a new bag, but the interest on the loan has gone up to 30,000 yuan, and the boy can no longer afford to live in the school anymore. The man tells him that if he goes to a dance party and does as the man asks, he will be given 50,000. The boy wonders if the man has supernatural powers, and if he can pay back the debt.
