After Three Hundred Years with the King of the Underworld, I Became a Human Heiress

I’m the woman the King of the Underworld can’t bear to let go of.

To be reborn as a wealthy beauty in the human world, I willingly stayed in the underworld to serve him.

After tormenting me for three hundred years, the King of the Underworld finally grew tired of me and granted my wish to return to the human world.

But just before I was reborn, I saw thirty years into the future.

My wealthy fiancé was holding the hand of a strange woman. He said she was the real heiress of the family, while I was nothing but an illegitimate child.

What a joke.

How could some fake heiress possibly ruin the wealthy life I’d worked so hard to get?
