After a monthly exam, the head teacher arranged for Wen Chuzhi, who was not good at math, and Zhou Jingmu, who was not good at English, to sit at the same table. In the process of getting along, Wen Chuzhi discovered that although Zhou Jingmu was among the top ten academics in his grade, he had some bad habits. During the week, Jingmu did not tidy his desk, memorized English words during the second lunch break, and shook the table while sleeping during the third lunch break. So Wen Chuzhi decided to make a three-chapter agreement with Zhou Jingmu. In the end, the three-chapter agreement became more and more entries, and finally ushered in its conclusion.
