His dad has been hospitalized and Nagomu worries no one would take over the family business - a Kyoto sweet shop called Ryokushou. He's surprised to find a young girl named Itsuka Yukihira is the shop's new poster girl and successor.

Itsuka's father abandoned her and she hopes to find him someday. Nagomu's mom asks him to act as Itsuka's dad, so she can have the hope of reuniting with her real dad. As Itsuka and Nagomu grow closer, their bond strengthens. With a shared love for Ryokushou and its confections, their relationship brings sweetness to the lives of those around them.
