In the kingdom of Woo, a single secret sets destiny into motion. On the night of her marriage, Queen Jae Won bears a child in silence, a son she abandons in the forest to protect her throne and bury her shame. That child, Hyun Woo, grows up far from the palace, unaware that he is the true heir to the kingdom.
Raised by a mysterious guardian with hidden motives, Hyun Woo learns of an ancient curse linking humans and demons, and of a sacred book said to hold the fate of both worlds. Meanwhile, in the palace, Prince Sung Hee is celebrated as the rightful successor, trained to wage war against the rising darkness—never knowing the truth of his birth.
As war spreads and the demon gate threatens to consume the land, Hyun Woo is drawn back toward his past. Alongside the brave and loyal Ye Jin, he must choose between revenge and redemption, destruction and peace. But the path to saving the kingdom demands a sacrifice that could cost him everything.
Betrayal runs deep, love is tested, and the truth can no longer remain hidden.
In a world where greed opened the curse, only courage, truth, and sacrifice can close it. What will Hyun Woo choose?
