A kid watches her family fall apart and gets one impossible chance to fix it by going back to the moment everything was still possible. The bus ride is gentle, strange, and full of small magic, but the real weight hits when you realize she can't actually change anything, only understand why things broke the way they did. It's a show about learning that love isn't something you can save retroactively, no matter how hard you try or how far you travel backward.
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.
