You were never meant to meet him.

As the heiress of a powerful company, your life was already full of threats, secrets, and betrayal. But the moment you were nearly killed in an “accident,” everything changed — because he appeared. A stranger with fire in his eyes and power in his voice: Jeong Gu-won, a demon who had roamed the earth for centuries feeding on human souls in exchange for their desires.

Except when he saved you, something strange happened. His demonic powers transferred into you — and now, the once-feared demon is powerless, bound to the one person he never expected to need: you.

To protect himself — and you — from the dark forces now hunting you both, he forces you into a contract marriage. But the hatred and tension between you slowly burns into something else. Something dangerous. Something forbidden.

Then, one night, passion takes over and find out you're pregnant. With a demon’s child.

No one, not even Gu-won himself, thought that was possible. The baby growing inside you is part-human, part-demon — and now everyone wants it. Hell wants to destroy it. Heaven wants to prevent it. Rogue exorcists, dark creatures, and Gu-won’s enemies begin closing in.

But Gu-won changes. He’s no longer just cold, distant, and sharp-tongued. He becomes obsessive, protective to the point of madness, always keeping a hand on your belly, whispering to your unborn child in the dark, threatening to burn the world if anything dares come near.

You’re carrying something impossible — a new future for both demon and human kind.

But can love survive prophecy, war, and the darkness inside both of you?
