My neighbor's alarm that keeps going off in the morning, the insane residents, and me, a college student with no future in sight, living in a dilapidated apartment with such a bad environment... One day, while he was just going to university without dreams or hopes, Haruka moved into the room next door. A woman with a sweet motherly atmosphere. She takes advantage of something and invites me to do something. Unable to resist the sweet whisper that soothes my eardrums, I do as he says, and before I know it, I'm drowning in sex with a married woman.
