In junior high school, Ning Yanbei was Zhong Qinyi's distant light. He was isolated by the whole class because of him, but he also learned to be strong because of his leaving without saying goodbye. In order to catch up with that light, she tried her best to get into the upper secondary school of Shanghai No. 1 Middle School, but she always missed him. Until the opening ceremony of the university, when he stood on the stage and delivered a speech, his eyes locked on her through the sea of people: "Zhong Qinyi, I have been waiting for you for a long time." It turns out that this pursuit of youth is a two-way street.
