A single mother bear, known as Kumama, raises her child alone in the forest, managing all parenting duties by herself. Her isolation eases when she meets two other animal mothers, a rabbit and a squirrel, and forms friendships that help her find joy in child‑rearing. A turning point prompts Kumama to move to the city, where she confronts a series of modern societal problems: securing preschool placement, finding employment, dealing with moral harassment and domestic violence, and navigating the challenges of two‑generation cohabitation. Despite these difficulties, Kumama’s easygoing and unflappable personality enables her to influence the people she encounters, gradually changing their perspectives and situations. The story follows her journey from solitary forest life to urban struggles, highlighting the realities of single parenting and social issues through a gentle, humorous lens. The main characters include Kumama herself, her child, and her mama‑friends the rabbit and squirrel, whose presence provides support and contrast as Kumama adapts to city life.
