Killer Peter / 킬러 피터

He was once the most feared executioner in the underground world, a legendary hitman who built the reputation of the ruthless Glory Club from the shadows. After decades of bloodshed, Peter hung up his guns, traded his blade for dusty bookshelves, and tried to find peace in the quiet life of a used bookstore owner. But the underworld has a funny way of refusing to let go.

Betrayed by the very organization he bled for, Peter is left for dead in a brutal ambush. He should have died, but fate had other plans. When he wakes up, the weary, aging killer finds himself trapped in the body of a teenager. Rejuvenated, lethal, and fueled by a cold, calculated rage, the old master of death is back in his prime. The Glory Club made a grave mistake—they didn't just try to kill a man; they gave a monster a second chance to finish the job. Strap in for a high-octane revenge thriller where a teenage body hides the instincts of a seasoned apex predator.
