What are the odds that Zavian, the son of the devil, would fall for the only woman whose destiny is to destroy him?

In the beginning of time, war broke out between the fallen angels and the devil, and the devil was defeated and cast into the underworld. During the war, Zavian, the devil’s son, turned against his father and joined hands with the other demons to defeat him, which made the devil kill his son’s wife as a punishment for betraying him.

But 500 years later, there appeared a woman slave who looked exactly like his wife, and Zavian, who had longed for his dead wife, couldn’t help but get drawn to her.

Even though everything in him screamed not to, Zavian stood up and walked past the princesses in front of him and to the maid;

She was tiny in her dress, and her whole body trembled as he approached her, her eyes pinned to her feet, afraid to behold his face. He smiled as he held her face, tilting her head to look at him;

“Neera, will you be my queen?”

And that was when all of hell broke loose…
