In this chapter, the protagonist, a junior high school student named Jean, tells his teacher, Armin, that he does not need him to stay in school after all. He tells Armin that he is not worried about his scores on the standardized test because he is so good at math. He also tells him that he has no choice since his scores aren't good enough to get into the teacher's class. He says that he knows this is not important to him, but that it is a crucial problem that needs to be solved. He asks the teacher to find out what his weaknesses were on the test, but the teacher doesn't seem to understand the loneliness and loneliness of an overachiever. He then tells the protagonist that the cost of food for his experiments and animal feeds come out of his pocket.
