I'm a college student with no future in a rundown apartment in a bad environment, with irrational residents who hold loud drinking parties from early in the morning... One day, while I was spending my days lazily without dreams or hopes, Tsumugi moved into the apartment next door. A beautiful woman with a somewhat seductive aura. She seduces me in every way possible... I can't resist her sweet whispers that melt my eardrums, and I become obedient and drown in the house-staying sex with the married woman.
