After her father left home, Anna lived with her sickly mother. Learning that the rent was overdue, Anna decided to become a home helper for their landlord to ease her mother's burden. The landlord, who is wheelchair-bound and inconvenienced, took advantage of Anna's offer to 'do anything' and repeatedly subjected her to sexual harassment. Initially, it was just caregiving, but his demands escalated, ultimately leading to him having sex with her and ejaculating inside. Although Anna initially resisted, she gradually became a sex slave.
