The hedgehog asks if he made the girl unhappy when she asked him if he was engaged. He apologizes for breaking her privacy by asking. He tells her that he is worried about her because the teacher told him about the marriage contract at the age of 18. The teacher tells him that alain does not plan to get married because he does not want to be chosen by his father, who is very fierce. He also tells the hedgehog that he has seen a handsome man in the art department and that he looks just like alain. The hedgehog guesses that the two men are brothers.
