The world ended with a whimper, not a bang, as a gargantuan asteroid obliterated everything we ever knew. Humanity had its shot, and we failed miserably. But what if the ultimate defeat was just the beginning of the real mission? Enter Cheol-su, an average, unremarkable office worker whose mundane life is about to be upended by a desperate, second-chance miracle. Thrust back into the past with the weight of the entire planet on his shoulders, he is the only line of defense against an extinction-level event. This is not your typical power-fantasy hero; this is a story of grit, high-stakes science fiction, and the agonizing drama of a man trying to change fate itself. Can one man truly rewrite the future, or are we all just waiting for the sky to fall? Dive into a gripping race against time where every decision ripples through history.
