Takashi was sent back to his parents' house after making his wife angry over a trivial matter. The more quickly I apologized, the more my wife's anger increased. I alone could not solve the problem. At that time, my wife's younger sister, Yuri, mediated the fight. Not only that, my mind was completely on Yuri, who listened to my worries about married life. He was treated by the beautiful and gentle Yuri, and the occasional fight between husband and wife was not bad. While I was thinking that, Yuri arranged a night.
