Moa Hoshizora works as a visiting caregiver. That day marked the first session of her special training. In today's aging society, caregiving services have become increasingly specialized, giving rise to a new form: "sexual visiting care" available exclusively to premium members. She delivers medicine through mouth-to-mouth, touches the aging male body, and offers her own body. Though called caregiving, behind the name lies lewd service. Moa awakens the "will to live" in these men by providing both healing and pleasure. The depth of this work, along with Moa's own emotions, gives birth to a new kind of relationship.
