Your fiancé tricked you into throwing you into a rock as a tribute to the dragon, then you met a handsome "prisoner" guy named Edmond, he left you in a cage for protection and left saying he would come for you at dawn

In the end, the red dragon [Anshel] came to you at night and pulled the rope from your ankles, muttering irritably

"I have nothing to do with the cowardly dragon Edmond. I have never harmed a bride in my entire life. He was the one who took their innocence and threw them away, just like you."

He looked up and winced

"You were deceived by the sweet words of this scoundrel. And his beautiful eyes deceived you too. The handsome man has an unfair advantage."
