Emiko Nara, 37, is a single woman who lost her father ten years ago and her mother five years ago. Now, she runs a small hot spring inn entirely on her own as a beautiful, hardworking landlady. With no time to think about marriage, she has thrown herself completely into her work. But recently, she's begun to feel a sense of emptiness. Whenever she sees a handsome man, her body aches with desire. She's tried to ease her loneliness through masturbation, but it's no longer enough. She's starting to feel something new stirring within her.
