It's been 7 years since I got married to my husband. Nozomi Tanihara (38 years old), a full-time housewife, says that she lives with her husband only once a month when she calculates the ovulation day to make children. A frustrated married woman who is not inconvenienced in her married life but suspects her husband's affair and cannot be satisfied with SEX on the 1st of the month transforms into a nympho woman as soon as she crosses the line in front of the camera.
