Died in the cold. Starved. Betrayed. Devoured by the very people he once trusted. In a world consumed by chaos, kindness became a death sentence—and Jae-min paid the price. Then fate broke its own rules. He wakes up 30 days before the apocalypse. This time, he knows everything: the endless winter, the rise of enhanced humans, the collapse of civilization, and the day those closest to him chose survival… over him. But the man who returned isn't the same. Cold. Ruthless. Unforgiving. Armed with future knowledge, an evolving spatial ability, and the deadly precision of a sniper who never misses, He prepares not just to survive—but to rule. As monsters emerge and humanity tears itself apart, he moves through the shadows, one step ahead and one bullet at a time. This time, he won't be abandoned. This time... he decides who lives.
