Jia Dongxiao (Huang Jinkun), who looks like Wang Baoqiang, has the same persistence and naivety as "Xu Sanduo". He longs to realize his dream in the big city, but he also endures the pain of renting a house in a group, having no money to eat, and being harassed by the sound of sex next door. Mi Xiaoxuan (Gu Xingyi), a non-mainstream girl, came from Beijing to Jia Dongxiao in a hurry. The two, who are not lovers, sleep in the same bed every night out of necessity. Punk girl Linlin (Wu Enxuan), after being dumped by her singer boyfriend, lives in a small house all day and is seriously autistic, which arouses the pity of her neighbor Jia Dongxiao. IT man Li Microsoft (Li Zhihao) earns more than 10,000 yuan a month, but he also rents a loft in an old alley with Jia Dongxiao and others. He is taciturn and has a boring life until Mi Xiaoxuan appears in front of him, and everything changes. Four young people who came to the big city to fight for their dreams, two sighing relationships, a story in which every urban outsider can find his own shadow. Four characters, some stay, some leave, there is bitterness, there is beauty, there is laughter, and there are tears of youth... a pitfall love, a miserable comedy.
