Introduction
In the fairy world, they were a loving couple because he was seriously injured and died for her. . . Let her fall into a demonic state and have no choice but to enter the devil's path. . .
But how can it be so easy to become a demon? You must go through four (death) reincarnations, cut off the roots of love, and cut off the source of immortality before you can become a demon. The test that allowed her to enter the devil's path turned out to be betrayal by her beloved, and she was reincarnated four times, each time she was born out of love and died out of hate. . .
