[Double strong/amnesia story/substitute story/past and present life/eccentric princess sick demon king vs cold, aloof, paranoid and overbearing ghost king]
The demon king who everyone in the world was shouting about traveled to a thousand years ago to attack the ghost king, her old enemy. It was a joke. How could it be possible? She didn't care. What happened to the ghost king in the future had anything to do with her. Anyway, she had accidentally crossed over. Looking at the young man with black hair and red lips in front of her, hehe...
