Xiangyang Middle School has started school. As a freshman in high school, Xu Yuan came to the new school with full expectations. In this chaotic world, Xu Yuan always believes in the existence of beauty. Chen Xun has a rich love history and has many ex-girlfriends. Xu Yuan thought that they would never cross paths, but unexpectedly the two became deskmates. After getting along for a semester, Chen Xun had different feelings for Xu Yuan, and Xu Yuan also liked Chen Xun more and more strongly. Until the second year of high school, they changed places and gradually lost contact. However, Chen Xun and Li Ruonan got closer and closer.
Until the senior year of high school, the two of them had not spoken much. On the day of their graduation, Xu Yuan sang two songs. Both songs expressed Xu Yuan's changes in feelings for Chen Xun.
Later, during the summer vacation, Xu Yuan experienced the darkest day in his life.
