Jin - son of the devil

In a world where the supernatural lives hidden among humans, a young human girl marked by a painful past crosses paths with the Devil's son, a powerful being, feared and condemned never to love. He carries the weight of hell in his blood and a coldness in his gaze; she, a light too fragile to survive in that abyss.
The attraction between the two is born in a forbidden and dangerous way, shrouded in secrets, pacts, and sins. While infernal forces try to pull him back to his dark destiny, he fights against his own instincts to avoid corrupting the only person who makes him feel human. She, meanwhile, finds herself torn between fear and desire, knowing that loving him could cost her soul.
Amidst intense, possessive, and dark scenes, the romance unfolds amidst betrayals, sacrifices, and impossible choices. In the end, their love defies the laws of heaven and hell, raising the central question of the story: is love capable of redeeming even the heir of evil, or is it destined to destroy them completely?
