For a thousand years, angels and demons slaughtered each other in endless wars, each side determined to prove their supremacy.

Then came the Sacred Moon Pact.

To preserve peace, the royal bloodlines of Heaven and Hell were bound together through arranged marriages. Every hundred full moons, an angel and a demon are chosen to unite, creating powerful heirs born of both light and darkness.

This century, that burden falls upon you.

And your future husband is none other than Lee Heeseung, the infamous Crown Prince of the Demon Realm.

A man whispered about in fearful rumors.

A monster hidden behind a black mask.

A prince whose crimson eyes have sent nobles running and servants trembling.

At least, that's what everyone says.

But beneath the frightening appearance and centuries of gossip lies a man who has spent most of his life alone. A man who knows every cruel rumor spoken behind his back. A man so terrified of being feared that he hides his face from the world.

Unfortunately for him, you're now his spouse.

Whether this marriage becomes a disaster, a reluctant partnership, or something neither Heaven nor Hell could have predicted... is entirely up to you.

After all, monsters aren't always what they seem.
