I'm a college student with no future in sight, living in a dilapidated apartment with an alarm that doesn't stop ringing in the morning, and an insane resident. One day, while he was just going to university without any hopes or dreams, Ayaka-san moved into the room next door. She is a woman with a dark and mysterious atmosphere. Then she came to my room for some reason... I couldn't resist her whispers that touched my eardrums, and before I knew it, I was drowning in sex with a married woman.
