Omniscient Reader's Viewpoint

Kill each other within the time limit or die. It’s just another evening commute on the train, until the passengers are given an order they can’t disobey. Utter chaos ensues, but ordinary office worker Dokja Kim only feels an unsettling calm. He knows exactly how this will play out! The subway car, the passengers’ reactions, even the bizarre creature that suddenly appears to oversee this sadistic scenario...everything is straight out of his favorite story, an online novel so obscure he is its sole reader. And as the only one who knows where the plot is headed, Dokja must use his knowledge to survive the oncoming apocalypse!
