Yoon Seong, who just got a job at JH Soft, is troubled by the CEO, Baek Hajin, who keeps glaring at him every time they cross paths. “Why does he keep glaring at a lowly employee like me? Did I do something to offend him?” Trying to avoid Hajin as much as possible, Yoon Seong does his best to stay under the radar... But one day, he discovers a mysterious employee ID badge— and learns the shocking secret that the CEO is actually a nine-tailed fox! To make matters worse, Hajin’s fox marble ends up lodged inside Yoon Seong's body and refuses to come out, leading to a work life that’s anything but ordinary! “You have two choices, Mr. Yoo Yunseong. One: stick close to me for a while and go through some annoying stuff. Or two: I cut open your belly and take it out.” Huh?! Aren’t both of those options way too extreme for an ordinary office worker like me?!
