Mahiro moved to Tokyo from the countryside in Kochi prefecture. Focused on her career, she lives a busy but fulfilling life. One night, she comes back home to see her ex-boyfriend, Tatsumi, stark naked with only a towel wrapped around his hips. What's more, he seems to not have realized they'd broken up! He reaches out to touch her, making her body remember the strong feeling. Even though she is still at the doorway, she gives in to his caress... Mahiro is frustrated. After all, she broke up with Tatsumi, not being able to take his conceit. Despite that, her body remembers that it belonged to him, making it impossible for her to resist when he initiates rough sex in the CEO's office.
