One day, he falls ill, making it difficult to continue working, and ultimately loses his job. Desperate and cornered, Yuya is presented with a cruel proposal by the yakuza member Takimoto: his wife, Mai, must join the worksite and also serve as a sex doll for the men. Unable to resist, Yuya has no choice but to accept. As a result, Mai is forced into a new kind of labor, enduring both grueling work duties and relentless sexual exploitation on the job.
