Haruka helps run the company her husband Hiroshi founded after leaving a major corporation. Just as the business begins to find its footing, their former junior colleague Aii asks them to assist with a new project. Hiroshi agrees, but during their first meeting he points out flaws in the project, damaging Aii's reputation and humiliating him. Furious, Aii demands one specification change after another, leaving Haruka to redo the documents for her husband. When another problem is discovered on the day of the deadline, Haruka apologizes profusely—only for Aii to order her to prove her sincerity with her body, beginning a disturbing tale of betrayal and cuckolding.
