Deaimon: Recipe for Happiness - S01

Ten years after leaving home to chase a dream that ultimately failed, Nagomu Irino decides to return when he hears that his father, who owns the Kyoto sweets shop Ryokushou, has been hospitalized. Fearing no one will take over the shop if his father dies, Nagomu prepares to accept his family's legacy and learn the craft of making sweets. Unsurprisingly, Nagomu finds that his father has already picked a different successor: a 10-year-old girl named Itsuka Yukihira, who was left at Ryokushou by her father for unknown reasons. She has become part of the family and now serves as the shop's poster girl, but she still wants to see her father and chases every clue that might lead her to him. Sympathizing with Itsuka, Nagomu's mother asks him to act as her father, hoping Itsuka will open up to him and ease her pain, even a little. Starting off on bad terms, Itsuka and Nagomu gradually get to know each other and realize they are more alike than they thought. Bound by their shared love for Ryokushou and its sweets, their relationship as child and father figure begins to make the lives around them a little sweeter.
