Mr. Kuramoto, who just got married last year, imagined a happy married life, but in reality, he seems to be living a very sober life. The main cause of this is the attitude of the casual husband, even if they eat together, there is almost no conversation, on holidays they are immersed in their hobbies alone, and the occasional night activity is sex that does not feel affection at all only to satisfy sexual desire. - Dissatisfaction with such a husband became the limit of patience, and as a solution to it, an affair spirit sprouted.
