She was just an unknown person in the world of immortality, but because of a reckless act three hundred years ago, she became entangled with him. And he is the future monarch of the demon world. He should not have met her, but because of an accident, he surrendered his heart out of love and hatred.
She has no intention, she doesn't love him, he has no intention, he doesn't love her. But why, she had a heart, and her heart was broken for him, and she would not hesitate to cut off the immortal relationship. He had a desire, and he would not hesitate to give up his position as a monarch because of her growing clothes. Sadomasochistic love is deep, maybe they can get what they want?
Intention: Whether you are a fairy or a demon, good or bad is the choice of your state of mind.
