In this short scene, Cang-dong tries to explain the school rules to Lin-ying. He tells her that students must not speak loudly in class, and that they must not leave class earlier than the end of the term. He also tells her to take an umbrella with her when she gets back from the dentist's office. She tells him that she has a high fever, and she has taken anti-inflammatory drugs and anti-pyretics to treat her condition. She says that she will be fine when she removes her wisdom tooth, but that she was rushing so much that she forgot to take her umbrella. He says that he came to her because he was worried, but he also wanted to stay with her. He thanks her for coming, and they go to the hospital.
