Chen Geng, a 42-year-old mechanical engineer, received a notice that his daughter had been dismissed from a private school on the day his wife filed for divorce. In order to keep his daughter's academic status, he had to pretend to be a couple with Mai Jinxi, the daughter of the director of a tertiary hospital in the same city. This female doctor, who wore pearl earrings and smelled of disinfectant, was actually his "enemy" who smashed his head with a wrench at the factory technical competition.
When Chen Geng discovered that Mai Jinxi's wedding ring was embedded with diamonds given by her ex-husband, and that his daughter was secretly imitating the other's daughter's piano fingering, this middle-class marriage game began to get out of control. The ruler used by the demolition office to measure the Chen family's old house late at night, the plummeting curve of the Mai family's stock, and the paternity test report hidden in the daughter's diary all reflected dazzling light spots on the glass curtain wall.
