Manager Sagawa is furious that Kasumi, the employee he wanted, married his subordinate Amamiya. Unable to tolerate their happiness, he fabricates mistakes and schemes to drive the couple apart. Amamiya cannot defy his superior and begins distancing himself from his wife as ordered. Confused by her husband’s sudden behavior and unaware of the plot, Kasumi turns to Sagawa for advice. He exploits her trust, pushes her further into emotional distress, and targets her through repeated forced overtime, breeding sex, and creampies.
