Before I turned 30, I was transferred to the Tokyo headquarters. My friends were jealous of me, but I was living a comfortable life at home and was fed up with it as soon as I moved. Furthermore, the porn-like moaning sounds that could be heard all night from the next room... When I left the house in the morning without getting any sleep, I ran into a man who had just come out from next door. When I called out to him to warn him, a beautiful woman came out of the room... ...The source of the moaning sound, which I thought was coming from a porn production, was the wife next door.
