In this chapter, we learn that sonoda is a traitor and that her brain functions are normal. We learn that she was bullied by her classmates, and that she did it because she was afraid of losing her position as the class president. We also learn that her parents are away on business trips, so she is unable to talk to them. She tells us that she has a crush on her new class president, Midori Tamura. She says that she had no idea that her sister was in love with him. She also says that now that she thinks about it, she realizes how old her family is and how her sister is doing in school. She promises that she will help her sister in any way she can.
