The hedgehog and the man don't really want to borrow money from each other. The man says he'll sell the bag if the man doesn't pay back by the end of the month, but he's not going to loan him any more money. He tells the man to go back to school and get a student's card at the university office for a discount. He's nervous about going back to the school, but the card has 30 yuan in it, so he can use it to go to the university and take more trips. He also wants to hire a personal assistant to help him adjust to university life, so the man agrees to hire him. He wants to give the man 3,000 yuan a month, which is too little, but now he has a "peace of mind" that he can do whatever he wants with his life.
