"The Cursed King."

This is my very first x reader! Y/N x Kageyama Tobio!

It all started with a young prince, destined to become the next King. Many of the villagers hated the prince because he was "cursed". That was when Prince Tobio finally found out he was cursed with a demon sealed inside of him. As him and his older sister, Miwa Kageyama, tried to find many ways to unseal the curse and kill the demon. Also with the help of Y/N..who is also the demon's daughter..Tho most fairy tales end with a happy ending, does Tobio's ending end well? Or is this a love story within him and Y/N.
