Miki Poyota anchors the series as its central maternal figure. Married to salaryman Gendai Poyota, she parents their two young children: five-year-old Hyōga in the oldest preschool class and three-year-old Jura in the youngest. Her days center on managing household duties while navigating the often humorous challenges of raising small children. The series title's "poyopoyo" captures the unsteady, toddling movements of young kids, a frequent source of comedic situations. Her experiences embody common parenting joys and difficulties, from addressing child behavior and balancing tasks to fostering family connections. She interacts with other families in their community, including the Kunitachis. The narrative consistently portrays her within family dynamics and child-rearing, maintaining focus on the parenting theme without expanding into significant personal backstory, external conflicts, or character transformation.
