Kokoro is a daughter who begs the landlord for a helper in place of her mother, who has fallen ill from overworked work after her father disappears and falls into arrears with debts and rent. The landlord, who is confined to a wheelchair and has limited mobility, takes advantage of Kokoro’s pleas, saying, “I’ll do anything,” to repeatedly sexually harass her. At first, it was just nursing care, but the demands escalated rapidly, and she ended up having sex with him. At first, Kokoro showed resistance, but gradually he turned into a sex slave.
