The peaceful life of Lu Fei (Chen Bolin), a Taiwanese animation designer working in Beijing, was broken by a drunk girl Ran Jing (Wang Luodan). Starting from a passive overnight stay, the stewardess Ran Jing seemed to be interested in this dull boy who held a "no love" attitude. After several contacts, Ran Jing shared Lu Fei's residence with a lot of bags and countless "co-living" rules. Lu Fei's comfortable single status came to an end. He was unwilling but gradually adapted to living and working under the supervision and care of Ran Jing. The arrival of the latter made Lu Fei's animation creation, which had been stranded for a long time due to lack of inspiration, turn around. Before Lu Fei had time to savor the sweetness of love, an accident forced him to make a choice that changed the trajectory of their lives... This film is adapted from the online novel "The Days of Living with a Stewardess".
