The Kanon family decided to move to a new home, settling in a particular neighborhood for the sake of their future children. However, wife Urara had no desire to get involved with the local neighborhood association. Despite this, she's constantly pestered by a meddlesome neighbor named Shibata, who pressures her into revealing her struggles with infertility. As a result, she's forcefully invited to a neighborhood meeting, and reluctantly agrees—along with her husband—to attend just this once. During the gathering, an appointment is secretly arranged for a rumored fertility-boosting massage that's said to increase chances of pregnancy in the area. For Urara, this marks the beginning of a nightmare.
