She starts to manage the business with the help of an old and experienced worker – Mr. Tame, who has worked for a long time in the public bath since Rinko’s grandparents left. However, this traditional public bath is no longer marketable in this new century. In order to solve this declining situation, Rinko thinks of a “Bikini Body Wash Service” but… Nao works as a part-time hot spring lady at “Matsunoyu”. She encounters Akira and falls in love with him. Now, Rinkyo, Tame, Nao and Akira do their best to get more customers their public bath. Meanwhile, Kazaki who had an affair with Rinko few years ago comes up to confront her.
