Maki Hojo is introduced to Yuuya, a local liquor store employee, by her neighbor and drinking buddy Yumi. Known for his hardworking nature and cheerful personality, Yuuya quickly wins Maki's trust. However, his hidden side gradually comes to light—Yuuya has been secretly sleeping with married women he delivers to. One day, he suddenly confesses, "You're exactly my type, Mrs." Though initially rejecting him, Maki, dissatisfied with her marriage, finds herself unable to forget the intense pleasure he awakened, and begins masturbating, reliving the sensation. Later, when Yuuya arrives for another delivery, she invites him inside. From that moment on, their relationship takes a new, intimate turn.
