Wife and executive at her husband's company, Shoko handles accounting and personnel, earning the trust of employees and maintaining steady business performance. However, her husband spends his nights drinking at clubs, leaving their relationship cold and distant, like mere business partners. One day, Shoko begins training a new young employee named Sayoshi—handsome, strong, and possessing innocent eyes—and gradually finds herself becoming aroused by him. When a business trip is arranged for an important negotiation, her husband asks Shoko to accompany him. But Shoko's true intention is to fulfill her own desires through Sayoshi. Under the pretense of training, her real goal is to satisfy herself with him on this trip.
