Sanao lives with her mother. Besides working at a factory, she also works as an assistant to the landlord. When her mother fell ill, Sanao decided to take over her job as the landlord's home helper. The landlord, who is wheelchair-bound, repeatedly asked 'I'll do anything,' and Sanao took advantage of this to commit sexual harassment. Initially, it was just caregiving, but his demands escalated, ultimately leading to sex with internal ejaculation. Although Sanao had resisted at first, she gradually became a sex slave.
