Vengeance of the Shadowed Heart

Kim Ha-jin’s life began in tragedy. Born to a mother rejected by her family, he lost her the moment he came into the world. Abandoned and unloved, Ha-jin was sold to a secretive organization at seven years old, where he became a test subject for inhumane experiments. Isolated in darkness and stripped of his humanity, Ha-jin emerged as a weapon, a shadow of a person molded into a mercenary.

By 21, he had lived a life of blood and betrayal. In a rare act of defiance, Ha-jin sacrificed himself to save a kidnapped girl, ending his life with a bullet to the head.

But death was not his end.

Reborn into a broken world as an abandoned infant, Ha-jin’s second life seemed just as cruel. His mother left him to chase her ambitions, and his alcoholic father sold him to pay gambling debts. By the time he was two, the world changed forever.

Gates—portals to monstrous realms—opened across the Earth, unleashing horrors humanity couldn’t fight. The appearance of the System, a mysterious force awakening supernatural abilities in a chosen few, gave hope. Ha-jin was among the Awakened, granted the rare Specter Class, allowing him to wield shadows as weapons and shields.

To the world, Kim Ha-jin became a hero, a symbol of resilience in the face of destruction. But in the shadows, he harbored a secret. Fueled by memories of his first life, Ha-jin seeks to dismantle the System, destroy the Gates, and exact vengeance on those who turned him into a weapon.
