Super no Ura de Yani Suu Futari

At age forty-five, office worker Sasaki has had enough of the corporate grind. His only solace is smoking-and the friendly smile of supermarket cashier Yamada. When Sasaki can't find Yamada after a particularly trying day, a striking woman invites him to smoke with her. The despondent man thinks he's made a new smoking buddy in the cool, teasing Tayama, but Sasaki doesn't realize he already knows her!
