Lin Chuan, an ordinary office worker, gains the ability to hear animals' inner thoughts after an electric shock. His own black cat, Doudou, becomes the most sharp-tongued "live commentator," pouring neighbor Su Wan's desires, coworker Chen Ke's repressed masturbation, and even the neighborhood dogs' commentary on last night's sofa noises straight into his head in real time. The ability makes it impossible for Lin Chuan to keep pretending to be a gentleman. After Su Wan comes to his door, he pins her down on the sofa; the next day at the office, the hamster Tuan Tuan kept by Chen Ke at the neighboring desk leaks everything—her phone holds over a hundred photos of him, and she masturbates in the restroom every noon. After overtime ends, Lin Chuan hears Tuan Tuan's breakdown complaint outside the men's room and is pulled into a stall by Chen Ke, who presses him from behind and does it. Afterward, Su Wan sends an urgent message: Doudou is missing.
