There is a loving husband who cares for her deeply and especially responds immediately whenever they both have sexual needs, but the wife Kanako does not appreciate it and has betrayed him many times. Perhaps she feels too bored and dull living and being in a relationship with a husband whom she has been with for nearly a decade, or maybe she is a promiscuous nurse who loves new things, so that is why. She begins to flirt with her colleague doctor to satisfy her promiscuous and lustful nature. Their secret encounters frequently happen behind the naive husband's back even though in the evenings they still interact normally.
