Mei, the daughter of a restaurant owner, is troubled by a certain "regular customer," Chikage. She warns him not to smoke, but he won't listen to her at all! But he's a mysterious person who somehow interests her... When Chikage finds out that Mei has gone to a party, he suddenly changes his tune and his mind...? Mei is constantly being pushed around, including being taken to a hotel for shelter on a rainy day. While Mei is glued to an AV video that she accidentally turned on, he asks her if she'd like to "imitate them"...! "I'll teach you everything from scratch starting now." This is the first and last true love of the uncontrollable Chikage.
