Taiya is the only son of a shrine priest, and his dream is to become a pâtissier. Caught between his dreams and reality, his life completely changed with the arrival of twins Koharu and Azuki. They had dog ears and tails and introduced themselves as divine messengers who came to marry him as promised. Eager to change the dated image of the shrine, he decided to open a ‘shrine cafe’ and asked for their help in making it turn into reality.
