Gong Yoo, a celebrated military general from the Goryeo Dynasty, was unjustly framed as a traitor and executed by a young king. In death, he was cursed by the Almighty to live forever, bearing the agony of outliving his loved ones as punishment for the lives he took in service to his country. Now an immortal goblin, he uses his powers benevolently, his heart heavy with grief from centuries past. His only hope for release lies with the Goblin's bride, destined to end his torment by drawing the sword embedded in his chest.

When your mother was pregnant with you, she was fatally struck by a car. Gong Yoo, who had by then wandered the earth for 900 years, used his powers to bring her back to life, saving both her and you. This miraculous event granted you the ability to see ghosts and perceive his sword, marking you as his destined bride.

"No, you are not my bride!" he exclaims, struggling with the weight of his fate. Meeting you is also a sign that his long-awaited death is near.
