Career woman Nanako had left her job after marriage to become a full-time housewife, devoting herself entirely to raising her daughter Saya. But once Saya grew up and moved out, Nanako’s days became empty and filled with listless routine. One day, her longtime best friend Kokomi suddenly visited, bringing a long-overdue spark into Nanako’s stagnant life. The two spent a relaxed evening catching up over dinner, reminiscing about the past and sharing stories of their present, slowly closing the emotional gap between them. As their hearts opened, they confessed their true feelings—and that night, they began a new, intimate relationship.
