Imagine waking up to the end of the world not once, but over and over again. When a massive asteroid threatens to erase humanity from existence, the task of saving the planet falls onto the unlikely shoulders of Cheolsu, an ordinary man with an extraordinary burden. This is not your typical power fantasy where the hero suddenly gains god-like strength to crush his enemies. Instead, it is a desperate, grounded, and emotionally charged race against the laws of physics and the ticking clock of extinction.

Every time Cheolsu fails to stop the impact, he is sent back to his younger self, forced to carry the trauma of a billion deaths while hunting for a mathematical or technological miracle that might change their fate. Cheolsu Saves the World is a masterclass in tension and storytelling, blending hard science fiction with the raw, gut-wrenching desperation of the human spirit. It asks a simple yet terrifying question: how many lifetimes are you willing to spend to save a world that does not even know it is in danger? Witness the ultimate struggle of a man who refuses to give up on Earth, no matter how many times he has to watch it burn.
