Fii was the first princess of the rural nation, Déman. One day, she became engaged to King Roy; an icy king with both beauty and ability, whose management ability was perfect, and who would be perfect save for his coldness towards women. The engagement was not really anything for her to celebrate though. Why? Because her younger sister with both beauty and fame, whose personality was great, who held a mysterious power and who was a soothing miko had gotten into a marriage of love with said king. And Fii, her twin, had just come along with her as a set bonus. She was treated as a stain on the fairy tale, but after a certain event, Fii decided she didn’t care any more. She didn’t care about this lifestyle where she never saw her husband even once, where she would spend the rest of her days rotting away in a royal villa. She was going to live her second life! That was the decision she came to.
