After getting divorced, Chisato Shoda helped out at her family's public bathhouse, which her father ran alone. One day, she witnessed a timid man being mocked by other customers over his underwear and stepped in to stop the commotion. Listening to his story, she learned the underwear had been chosen and left behind by his late mother—and that she herself bore a striking resemblance to her. That was why, despite the ridicule, he continued coming to the bathhouse. Embraced by his tale, Chisato's maternal instincts awakened, and she gently took him into her arms, healing his emotional wounds. She also warmly cared for other men with troubled pasts—such as a con artist about to turn himself in and a debt collector—soothing their hearts with tenderness and compassion.
