In this chapter, we learn that Shu-Bin is trying to get her brother to admit that she's a better person than he is. She's trying to make him feel better about himself, but he doesn't want to admit it, because he's afraid that he'll get into a fight with his sister if he does. He tells her to ask someone else who's better than him, so that he can feel better himself. He also tells her that she should ask someone who is better than her, because she'll be happy, too, since everyone else will also be happy. He then asks why she was so angry with him, and she says that she was trying to provoke him, but that she didn't mean to do it. She also tells him that she has been looking at him like that for a long time, and this time, she used the old man as an excuse to hurt his sister. He says that he no longer wants to be like a fool, and that she crossed the line today.
