[Two souls in one body + reincarnation of old enemy + falling in love and killing each other]
Humans and demons are old enemies, and they have the same mind. The good-for-nothing girl controls the big demon to death, but when the big demon looks at her, he remembers the woman who sealed him with a curse thousands of years ago.
It turns out that the fate of old enemies has been forged thousands of years ago.
"Good and evil in this world are never determined by race, but by human heart."
"Then I will give you my heart and let you decide."
Double c, men are attracted first
Purpose: Peaceful coexistence between humans and demons
