Mei, Aiko, Asami, and Nagi are making cookies at Mei's house. Knowing that the process could take a while, Nagi chases Yamato out of the house. He receives a text from Kai, who asks him if he wants to meet up at the park. When Yamato arrives, it is revealed that the rundown park was where the two of them first talked and bonded for the first time. After bantering a bit, Kai asks Yamato why he, who had always seemed to be having fun with a large crowd around him, was always the first one at the park after school. Yamato admits that he used to feel like he was a chameleon; someone who didn't have his own personality and just changed himself to please others. Kai tells Yamato that he used to hate the town, but thanks to Yamato, he now finds it to be beautiful. Kai reassures him that he is his own person, and Yamato confesses that after he met Mei, he realized just how lonely he was. Kai later runs into Megumi at the bus stop. They start talking, and Kai tells her that he thinks she's cool for staying true to herself while modelling. Megumi snaps back at him, and Kai, offended, leaves. When Momo comes, Megumi regrets lashing out on Kai and later becomes embarrassed when Momo suggests that Megumi likes him. At Mei's house, the cookies are done and turn out to be delicious. Mei's mom shoos Mei and Yamato out of the house. Yamato hugs Mei and tells her he's glad she's with him. They watch the sunset together before continuing their walk, holding hands.

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]

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]
