An adult college student lives in a run-down apartment, worn down by noisy neighbors, a part-time job that schedules him whenever it pleases, and a life with no dreams or direction. Then a beautiful, mysterious woman named Kana moves in next door and keeps finding excuses to invite him over. Unable to resist the married woman’s sweet whispers, he holes up with her and loses himself in days of decadent, intense sex—until he neglects college so badly that he has to repeat the year.
