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.
