Shizuka is a successful, career-driven woman. But, unbefitting of her pristine appearance, her apartment is a total mess. A friend, unable to accept the sorry state of her friend's place, books a cleaner to come and sort it out.

But on her doorstep Takumi Yotsuya, her former junior-high-school classmate appeared. The boy to whom she had once said hurtful things deftly cleans her apartment and comes across a very embarrassing personal object. Mortified, Shizuka agrees to do anything Takumi says as long as he doesn't tell anyone. His reaction is to bring her close and lick her ear. The once timid and effeminate Takumi has grown into a hunk of a man... one that drives Shizuka wild!
