Ten years ago, Jiang Xiaobai lost all his memories due to a traumatic event he no longer remembers. Now working as a trainee in Editorial Office No.2 of Wen Zheng Magazine, a literary periodical based in Chongqing, he is excited to begin a new chapter of his life: in two days, he finishes his probationary period and officially starts his job as an editor. He gives no thought to his recurring dream of a girl whose face can never clearly see. That evening, one of Jiang Xiaobai's seniors passes him the task of rushing to the airport to escort the idiosyncratic rising author Tong Li, who has returned from America to launch her first serialized novel in Chinese. As punishment for this senior reneging on his own duties, Jiang Xiaobai replaces him as Tong Li's new editor. Though they get off to a rough start, Tong Li soon recognizes Jiang Xiaobai as someone precious from her high school days. Before they know it, the wheels of fate are set in motion, as Jiang Xiaobai slowly uncovers clues about a long-forgotten girl from his past. [Written by MAL Rewrite]

Jiang Xiaobai has regained his memories, and Tong Li cannot bring herself to face him. Separately, they confront the truths left unsaid for 10 years—about the band September, to which Jiang Xiaobai and Mu Xiyu dedicated their youth; about the love triangle between Jiang Xiaobai, Mu Xiyu, and Tong Li; and about the painful circumstances that brought the trio together and ultimately led to the terrible tragedy that occurred on the day Tong Li left for America. At the end of it all, can Jiang Xiaobai and Tong Li accept the past and face the future together? [Written by MAL Rewrite]
