Character Arc
Kim Shin is a celebrated military general of the Goryeo dynasty whose loyalty is repaid with betrayal and death. Resurrected and cursed by a higher power, he becomes an immortal goblin, doomed to watch loved ones age and die while he endures alone. A sword embedded in his chest can only be seen and removed by his destined bride, an act that would finally grant him the rest he longs for after centuries of solitude.
Living in the present day with vast wealth and a Grim Reaper for a housemate, Kim Shin carries himself with elegance, dry wit, and deep weariness. His encounter with Ji Eun-tak, the young woman who claims to be the Goblin's bride, reawakens both hope and dread, since the end of his curse also means the end of his life. Their relationship grows from disbelief and teasing into profound devotion.
Across the series, Kim Shin must reconcile his desire for peace with his growing love for Eun-tak and his sense of responsibility toward those around him. Themes of sacrifice, memory, and the meaning of an endless life run through his arc, and Gong Yoo's restrained yet emotional performance made the character one of the most iconic romantic leads in Korean drama.
