Mr. and Mrs. Yabuki ended up living in the countryside due to work. Although it was an unfamiliar environment, he was supposed to lead a fulfilling life every day. However, Mr. and Mrs. Yabuki were holding their heads over the noise made by the thug-like people who lived in the next room. His wife, Kyoko, who has a strong sense of justice, recklessly warned him, and the noise soon subsided. I was relieved, but after that my wife came to contact me frequently. I had a bad feeling. When I finished work early and returned home, I heard the conversation between my neighbor and my wife having sex, and even making fun of me.
