Imagine being trapped inside your own body for ten agonizing years. Ten years of absolute helplessness, locked in a vegetative state with only your hearing and your thoughts to keep you company. No way to move, no way to scream, and no way to die. This was the living hell forced upon Kim Hyunsung, a brilliant model student who had it all: top-tier grades, striking looks, incredible combat skills, and an unwavering sense of justice. But on the very eve of his graduation, his life was shattered when he was pushed off a rooftop by ruthless bullies.

Just when despair threatened to swallow him whole, the universe cracked open. Hyunsung opens his eyes to find himself back in his high school classroom on the exact day the nightmare first began.

But the model student with the kind heart is gone. In his place stands a man forged in a decade of mental torment, ready to unleash absolute devastation on those who crossed him. This is not just a story about survival; it is a calculated, bone-snapping masterclass in retribution. To defeat the monsters of his youth, Hyunsung must become a devil far more terrifying than any of them could ever imagine.

If you are looking for a dark, deeply satisfying psychological thriller packed with intense, beautifully illustrated martial arts action and a ruthless protagonist who refuses to show mercy, this series will keep you on the edge of your seat. Buckle up and witness the ultimate execution of karma.
