<Established Theory: Unsatisfied housewives will sleep with you if you treat them like women!> A male college student works part-time alongside married woman Ichika, a part-timer at the same job. Though she constantly complains, Ichika always treats the young student kindly. One day, they end up alone together. As they chat like usual, something suddenly shifts—Ichika initiates a kiss, which quickly escalates into full-on sex. From that day on, they begin a secret affair, indulging in passionate encounters nearly every day. Despite overwhelming guilt and the taboo nature of their relationship, an irresistible attraction grows stronger between Ichika and the student.
