Not the exact book but close enough. This is my first foray into manhwa, South Korean comics, and it did not disappoint. Dokja Kim is the only reader of an online novel that has over 3,000 chapters. On the day he finishes it, everything changes—the world ends & he suddenly finds himself in the story. He is the only one that knows what happens next & how the world will end. Entertaining story, great art & I‘ll definitely keep reading.
