Mong-ryong, a brilliant and stunningly handsome secret royal inspector in Joseon, is sent on his first mission with full confidence. But his destination? None other than Namwon, a region plagued by the notorious pervert governor, Byeon Hakdo. While trying to expose corruption, Mong-ryong finds himself in serious trouble—he’s about to be forced into serving the lustful governor. Just when things look dire, a strapping local official, Ibang, catches his eye. Thinking quickly (and a bit shamelessly), Mong-ryong grabs Ibang and declares, “Take responsibility! You’re the one who made me like this!” If he’s going to fall into a man’s arms, he figures, he might as well choose the better-looking one. What starts as a scheme to escape danger soon spirals into chaos, confusion, and unexpected sparks. Will this rookie inspector survive Namwon’s corruption… or lose his heart in the process?
