Exchange student Li Xiaoli (played by Xie Chengze) came to the remote "Fujianobe" in Tokyo, Japan to study for a year. He was dull and wanted to work but repeatedly hit a wall. Finally, with the help of his old classmate Qiu Qiu (played by Qiu Tian), he found a Chinese restaurant. The acting store manager Guan Wei (played by Qi Xi) took him in and took care of him, the clerk Qingmu (played by Niu Chao) regarded him as a rival in love, and the chef Lao Wan (played by Chen Yongzhong) and the young chef Song Ge (played by Song Ningfeng) in the back kitchen ignored him... Li Xiaoli's arrival broke the silence of the underground floor and was involved in everyone's life. Time flies. Before the next spring comes, some people stay and some leave, and where will those "limited family ties, temporary friendships, and quasi-love" that have just been formed go?
