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.)

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?”
