Only he has read the ending... and now the world depends on it! As an office worker with a difficult life, Dokja Kim's only passion is an online novel so dark that he is its sole reader. But one day, the story comes to an end, and so does the world. People across the globe begin to be slaughtered by horrific monsters or forced to fight each other in sadistic scenarios ripped straight from the novel. However, only Dokja knows that this is just the first chapter of what's to come. Knowing the devastating twists and turns that lie ahead, he can no longer afford to sit back as a mere reader—it's time for Dokja to take the reins and write his own destiny!
