S01E01 Nagomu and Itsuka
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...
One day, with Christmas near, a message and a fir tree sent by Itsuka's mother arrive. Remembering back to the broken promises from when she was little, Itsuka is afraid to make another promise with her mother. But Nagomu's words give her a push, and she tells her mother that she'll be waiting. Yuzu yokan causes Nagomu to remember a conversation he had with his grandfather.
Nagomu Irino returns to his Kyoto home for the first time in ten years when his father is hospitalized. Nagomu is eager to take over Ryokushou, the family's Japanese sweet shop, but he's instead asked to be a father figure to Itsuka Yukihira, the girl everyone calls the successor.
