Once every thousand years, the Blood Moon and the Snow Moon rise — and with them, heirs are touched by forbidden magic.
In a kingdom ruled by power, fate chose two souls born beneath the opposing moons.
Wangyeon, the cold and powerful illegitimate son of a ruthless king, was born under the Blood Moon. Marked by dark energy and haunted by a crown he never wanted, he is feared more than respected… and trusted by no one but the older brother he quietly adores.
Jang Mi, a hidden girl raised in the shadows of a sacred temple, was born beneath the Snow Moon — the feminine, pure opposite of Wangyeon’s cursed power. After witnessing her family’s massacre, she is taken in by a secretive monk and trained in secret to wield the ancient energy flowing through her blood.
As secrets fester in the royal court and forbidden magic awakens, the kingdom of Haneulguk teeters on the edge of war. Wanghain, the beloved elder prince, masks his hunger for the throne with a gentle smile — even as he delves deeper into black magic that threatens to consume his soul.
When prophecy, power, and betrayal entwine their destinies, Wangyeon and Jang Mi must choose: will they destroy each other… or save a kingdom fated to fall?
