The world's only witch, who was called a villainous lady and had her engagement broken off due to the crown prince's change of heart toward his sister, now lived a slow life in a tower on the frontier. One day, a prince who was a descendant of the sister who once betrayed her came to visit...

I was once called a villainous girl who was betrayed by the crown prince, my fiancé, and the sister I loved most in the world, and was sentenced to execution as a woman who attempted to poison my sister. Just before my execution, I awakened as a witch, and now I spend my days alone atop a high tower deep in the forest. I am a witch who fulfills people's wishes in exchange for a price. Only once every few hundred years does someone come to the tower, and I had been spending those long days alone with nothing but boredom. Then, a young man introducing himself as a prince arrived with a face resembling that woman I once hated, with eyes the same color as hers, asking me to grant his wish.
