Having lived together for a long time without feeling happy, especially for Enami and her husband, every time she felt desire, her husband would refuse, citing tiredness. Frustrated, she turned to Hojo, the wife of her neighbor, to share her feelings. After hearing her story, both decided on a crazy plan to swap husbands. It sounds absurd, but it was true because they believed that men often get bored with what they own and are, of course, curious and want to explore new things around them. As expected, after swapping wives, both husbands became interested in sexual relations again, as evidenced by the fact that not only did they not refuse but were also very enthusiastic and actively sought to make love again with their 'neighbor's wife.'
