Takashi has been sent back to his parents' home after making his wife angry with something trivial. The more I rushed and apologized, the more my wife's anger amplified, and I couldn't solve the situation alone. At that time, my wife's sister, Yuri, came out to mediate the fight. Not only that, but I completely let my mind go to Yuri, who listened to my worries about married life. He is healed by the beautiful and gentle Yuri, and sometimes the couple fights are not bad. As I was thinking so, Yuri set up a night.
