In this chapter, we learn that Caius's sister, Lilia, is crying, and Caius is shocked to see her cry. He tries to comfort her, but he is unable to do so because he is afraid that she is crying because she is unhappy with her life. Caius tries to calm her down by telling her that he has gotten a lot of girl's signatures today, and that she should not worry about her back, because it is not good. He tells her to stop running around, and she responds by saying that she will be his best friend in the future. She then tells Caius that he should stop talking nonsense, and apologize to her for bumping into her and her servants. She tells him that he is just pretending to teach a monk how to ride a horse at midnight.
