In front of Kyoto Station, Yukihira Itsuka mistakes Irino Nagomu for her missing father. She never imagined that he was the son and heir(?) to a wagashi shop called Ryokushou—the same shop where she's been staying. When Nagomu and Itsuka begin working together at Ryokushou, they run into a little trouble.

Horikawa Mitsuru, a high school student, works at Ryokushou with Itsuka. Seeing the two of them chatting happily together by the sink makes Nagomu feel a little jealous. While Mitsuru works part-time at Rykoushou to help supplement her large family's finances, she's also actively making music. And her musical activities kick up some trouble.

One morning, on her way to school, Itsuka spots someone who looks like her father getting on a bus. She gets on the same bus to see if it really is him, but ends up falling asleep.

Faced with that, she can't find a way to be upfront and cheer Nagomu on now. Meanwhile, Nagomu begins kicking up a fuss about losing his headgear from his band, Chestnut Manju. With Kanoko and Itsuka's help, Nagomu searches for it, but...

For Itsuka's birthday, Nagomu uses his "Going Somewhere Together" ticket and takes her to Hirakata Park. While out with Nagomu, Itsuka's remembers when she went to the park with her father. When they get back to Ryokushou, they find a wagashi cake and birthday party for Itsuka waiting for them. Itsuka always seems to be chasing after the shadow of her father. Concerned, Nagomu comforts her. And in reply to Nagomu's words, Itsuka...
