The story takes place on a wonderful night in Changsha. Night owl Jing Weiwei (played by Yin Fang) met He Xixi (played by Zhang Jingyi) who was about to leave his hometown tomorrow morning in a bookstore, and the two agreed to go out for a night tour together. He Xixi talked about his half-brother, talk show actor He An (played by Zhang Yixing). At tonight's performance, He An's father (played by Luo Gang) appeared in the audience, and the two parted unhappily. On the other side, Chen Qingzhi (played by Bai Yufan), Liang Baoqi (played by Zhou Siyu), and Lao Xie (played by Wu Jun) guarded the Ferris wheel. They admired the night view while lamenting that it was not easy to work. The night was getting deeper, and this night was also the last time that the Internet celebrity food stall owner Li Jie (played by Su Yan) was in charge of making noodles. She decided to let her apprentice Xu Ge (played by Wu Haochen) take over and continue to run the food stall. The night is about to end, and a group of people sit together in a food stall slurping noodles. Encounters, love, staying, leaving, reconciliation, and reunion all happen in this city, and everyone has found a reason to love this place deeply.
