It hands a grade-schooler the one thing no kid should have to carry: a front-row seat to her own parents before she existed. Ichigo boards a magical bus after school and steps out in the era when her mother and her real father first met, which means every warm moment she witnesses is a moment she already knows the ending to. That's the quiet cruelty at the center of this thing, because the dad waiting for her at home is a step-father, and loving him and wanting the past rewritten are not the same wish. Five episodes, no spectacle, no stakes bigger than one family staying in the same room. It works because it never lets Ichigo be cute about it, she's just a small person doing math on adults who never explained themselves. Slept on, and the people who found it don't shut up about it for a reason.
Young Ichigo watches her parents drift apart, their marriage crumbling before her eyes. When a mysterious bus driver appears after school with an impossible offer, she boards a vehicle that defies the rules of time itself. The bus carries her backward to a pivotal moment: the early days of her mother and real father's relationship, before everything fell apart. Stranded in the past, Ichigo realizes she might be there for a reason. Perhaps she can influence the choices that led to heartbreak, nudging small moments in a direction that keeps her parents together. But meddling with the past proves complicated. She cannot simply rewrite history, and each decision carries consequences she cannot predict. What unfolds is equal parts adventure and quiet reflection. Ontama balances magical wonder with the very human pain of family dissolution, asking whether love can truly be salvaged or if some separations are inevitable. For viewers drawn to stories about second chances and the weight children carry when their families fall apart, this short series offers unexpected warmth.
