Two weeks have passed since the nephew of Professor Lu moved into his house below, and the old man wonders why he feels so bad. He asks his brother why he is late, and he tells him that he has run into a problem. He tells his brother that he did not know who the owner of the bear was, so he took it to the office downstairs. The old man asks if he has to go to school so early, and his brother says that he just met a student in the corridor, and that he mistook him for a bear.
