Video information
Girl Sijiu (Guanying) and Malin (Yunan) work at the same company and live in the same apartment. One has a gene that makes her extremely sensitive to "dirt" and suffers from obsessive-compulsive disorder, while the other has a gene that makes her prone to obesity, requiring medication to control her weight. Both struggle with the inability to establish stable relationships with others. When Sijiu reunites with her first love, Anteater (Hedongdong), and they happily rekindle their romance, his casual sloppiness makes it difficult for her to move forward. Malin's boyfriend (Yilun Lin) sees her only a few times a year, and her desire for more frequent contact leads her to be secretly adored by the sunny boy next door, Little Bear (Yuyan Peng). In order to find true happiness in love, the two decide to take medication to modify their genes. Afterward, their genes are corrected, but new problems soon follow.
