In the prosperous and unknown "Cloud City", two people who had nothing to do with each other started an absurd and warm 21-day misaligned life because of a mysterious antique mirror. The socially fearful and introverted illustrator Lin Xiaoman wakes up every day and finds himself in the room of the free and uninhibited guitarist Jiang Che; and Jiang Che wakes up repeatedly in Lin Xiaoman's nest filled with paintbrushes and dolls. From the initial dislike of each other, the two were at odds with each other, to later being forced to cooperate and understand each other. They have 21 days to find the cause of the mirror misalignment or risk being trapped in each other's lives forever. In this process, they not only have to deal with each other's weird work and social life, but also hide this huge secret. A series of hilarious and heartbreaking stories unfold, and love also quietly sprouts in the misplaced time.
