Her father ran away from home in debt, and Nana lived with her mother. I decided to become a housekeeper for the landlord to ease my mother's burden even a little. The landlord, who was disabled and in a wheelchair, repeatedly sexually harassed her, taking advantage of Nana's pleas: "I will do anything." At first, it was just nursing care, but the demands quickly escalated, and in the end, it even involved vaginal sex. Nana was initially resistant, but gradually turned into a sex slave.
