Plot

The series is set in a Kyoto wagashi store. The protagonist is an only son, Nagomu Irino, who has dreams of becoming a member of a band, and ran away from home to live in Tokyo ten years ago. He receives a letter from home stating his father is in the hospital and asking him to take over the family shop, so he gives up on his dream and returns home.
While he's been gone, however, a ten-year-old girl named Itsuka Yukihira has started working in the shop. Nagomu's mom, having become a foster mom to Itsuka during the time that Nagomu was seeking his dream as a band member, declares that there will be a contest between Itsuka and Nagomu to see who will take over the family shop.
