A high school kid raising his toddler brother after losing both their parents could be tragedy. Instead it's the gentlest thing you'll watch all year. The show never feels obligated to earn your emotions through conflict or plot, it just lets you sit with two kids learning how to be a family again, one small moment at a time. Ryuuichi's patience with actual toddler chaos feels lived-in because the animation treats children like real people, not cute props. By the end you'll rewatch it not for story, but because it costs nothing to be in that daycare room again.

Ryuuichi Kashima is a high schooler forced to grow up fast. After a plane crash takes both his parents, he becomes the guardian of his toddler brother Kotarou. At the funeral, the chairwoman of Morinomiya Academy, who lost her own son and daughter-in-law in the same crash, offers to take them in. There's a catch: Ryuuichi must work at the school's daycare center as a babysitter to earn their keep. The daycare exists to help teachers at the academy who have small children, but it badly lacks staff, so Ryuuichi becomes the first member of a new babysitter club. Now he is responsible not only for his quiet little brother but also for a group of toddlers with big personalities, in a gentle slice-of-life comedy.
