An office worker obsessed with a web novel called "Three Ways to Survive the Apocalypse" gets the shock of his life when the story starts happening around him. Kim Dokja has spent over a decade reading about Yoo Joonghyuk, a hero who keeps regressing in time to escape deadly scenarios staged for the entertainment of godlike beings called Constellations. Just as Dokja accepts that the tale is finished, a strange message from its author arrives, and the fiction turns real. He alone knows how events will play out, but that knowledge does not promise survival. Now he must use his reader's insight to change the course of the story, and perhaps finally become a protagonist himself.
