Moa works as a visiting caregiver. It was the first day of special training. As the population ages, a new type of specialized care service has been created - 'sexual visiting care', available only to high-paying members. She gives medicine by mouth, touches the elderly man's body, and offers her own body. It is a lewd service in name only. By providing healing and pleasure, Moa revives the men's 'will to live'.
