One day, 'Yul', the president of a "different world dump truck office", for the first time kills the one who is not his target, 'Kwon Yoo-jun'. Yul, who entered a romance fantasy novel to rectify his mistake, tries to return Yu-jun, who has become a villain, to the original world, but various events twist and end up trapped in the novel. After being scattered with the office staff, Yul, who does not know the specifics of the novel, tries to find a way to escape, but is in trouble because of Kwon Yoo-Jun, who talks nonsense about living as an aristocratic lady in a new world.
