Irene, a modern-day pastry chef, wakes up in a medieval fantasy world, only to find herself running a tiny bakery in a remote village. All she wanted was to bake in peace, but fate had other plans when she catches the eye of the cold and aloof Duke Castiel. To survive, she uses her modern knowledge to revolutionize the food industry and build infrastructure, all while getting wrapped up in the Duke's ambitions. As their business empire grows, so does their romance—complete with misunderstandings, enemies, and plenty of drama. When Castiel becomes Emperor, Irene goes from "pastry chef" to "duchess," and together they fight, love, and laugh their way through a chaotic yet sweet adventure!
