In this chapter, we learn that Caius's mother wants to have a baby girl, so she has a boy. When Caius is born, he finds nothing unusual in his sister's appearance, but when he finds out that she is a boy, he begins to care less for her. Caius explains that he only cares for his younger sister because she is prettier than him, and that when he realizes that she likes boys, he will be as good as Caius. He tells Caius that he must break off his relationship with a guy if he wants to continue to be friends with him.
