After Xia Ran came here, she became the same tablemate as Jiang Chen. There were jokes in the early days due to the difference in thinking about "science vs. Liberal arts" (for example, when Jiang Chen helped Xia Ran solve math problems and used super-outline formulas), the two gradually got closer in the process of "organizing wrong problem books together" and "sharing headphones to listen to music during class." The school held a sports meeting, and Jiang Chen was injured in a basketball game. Xia Ran took care of him throughout the whole process, and the relationship between the two warmed up. Before the college entrance examination, Jiang Chen fell into anxiety due to family pressure. Xia Ran encouraged him with "his advantages" recorded in his diary. In the end, the two agreed to apply for a university in the same city. At the graduation ceremony, Jiang Chen secretly inserted a confession letter into Xia Ran's diary.
