Mio is 42 years old. At a school reunion where she took a break, she fell into an affair with Ichijo. Even though she knows it's a bad relationship, her immoral feeling embraced by a man other than her husband turns into pleasure, and Mio falls into a spiral of adultery. As she repeats her affairs, her reason for her Mio becomes unstoppable, and her husband also devotes her asshole, which has never been inserted, to Ichijo. "Dear, please forgive me... I can't go back anymore..." An adulterous drama of a married woman drowning in desire.
