Book excerpt: Ichiko and Otoya are a married couple in their 30s who, despite getting along just fine, are completely sexless. Their solution: the authorized, extra-marital romance system (in other words, authorized cheating.) Unable to bear the sight of her husband lost in the giddy throes of romance, Ichiko—whether out of jealousy or sexual frustration—books her first appointment with a male prostitute. Meanwhile, Otoya's girlfriend Mitsuki is finally brought down under the weight of her taboo affair in this thought-provoking work which asks the question, "What should marriage truly be like?"
