In my previous life, I made an agreement with the Demon King to be together forever. Will it still be valid in this life?
If it works, then how come I hugged each other, had an affair with the young master of the demon clan, eloped with my childhood sweetheart, and became the evil lord's henchman?
If it doesn't work, then why do I kill those who love me one by one and pursue the traces of the devil?
The unruly fairy PKs the devil, who is the evil boss?
