A married woman, Yuna, who has been married for several years in an in-house romance. The married life was amicable and there was nothing dissatisfied, but …. From a certain point, her husband tends to leave the house due to overtime work, and Yuna becomes indulged in masturbation from frustration. In addition to that, recently, I started to feel someone's gaze in the locker room and asked my boss for advice. After that, I was asked about the identity of the gaze that my boss couldn't see. Unable to hide her surprise and bewilderment at the unexpected true culprit, she was attacked by an unexpected nightmare.
