A man comes home after a decade away to reclaim his family's legacy. He finds instead that he's been replaced by a ten-year-old girl nobody expected him to love. The show knows this isn't a story about sweets, it's about the quiet devastation of realizing what you thought was waiting for you was never yours to begin with, and how you choose to show up for someone else's dream anyway.

Nagomu comes back to Kyoto after a decade away, having given up on his music dream, and hopes to inherit Ryokushou, his family's traditional sweet shop, while his father is in the hospital. His father has other plans. The shop already has a chosen successor: Itsuka, a ten-year-old girl whose father left her there and never returned. Nagomu's mother asks him to act as a father to her. Itsuka resents him for leaving the family and insists that she, not he, will run the shop one day. What unfolds is a quiet story about two people learning to fit into each other's lives through a shared love of sweets. Starting off on the wrong foot, they slowly find they have more in common than either thought, and their bond brightens the lives of those around them.
