My wife Reiko is having an affair with her subordinate, Hada. I've been living alone for work for two years, and when I returned home, I felt relieved seeing Reiko's usual demeanor. However, I soon discovered the shocking truth—that during my absence, she had grown intimately involved with her junior colleague. Overwhelmed by intense jealousy and rage, I unexpectedly felt my long-dormant erection return, consumed by a strange, perverse excitement. Driven by this deep craving and obsession, I manipulate Hada into assaulting Reiko, setting in motion a twisted new chapter of betrayal and desire.
