I'm a college student living in a rundown apartment with a bad environment: the alarm clock ringing every morning, the host club bringing over their acquaintances every night and partying like crazy. Then, one day, Kinoshita-san moves into the apartment next door... A beautiful woman with a somewhat seductive aura. She keeps inviting me... I can't resist her sweet whispers that melt my eardrums, and I do as she says, drowning in a night of nest-style sex with a married woman.
