Shuujirou and Haruka have been married for 2 years and they seem to have an ideal marriage everyone else would dream of. They seem happy and they do love each other. But contrary to Haruka's idea of "a happy family with children", Shuujirou's sexual desire starts getting distorted under pressure. The difference in their feelings starts to show in their sex life… Shujiro starts to imagine his loved one having sex with someone else rather than himself in order to climax. One day, Shuujirou spills his dark desire that's been building up.
