A demon that was unleashed by a deity into the human world has opened the doors to the parallel world. A modern day Korean Emperor(Lee Min Ho) tries to close the door and seeks the help of a Detective, Jung Tae-Eul (Kim Go-Eun) who will do anything to save the people she loves.
Amazing, interesting, out of this world drama!! This plot is so good, that every character has an opportunity to outstand. The formidable actor Lee Minho is superb in his interpretation of Lee Gon, the leading character that keeps the whole story together. I would fall short if I were to describe the way this story grows and how tremendously good are the performances of Lee MInho and Kim Go Eun. This #theking_eternalmonarch is 1000% entertaining and keeps your interest growing episode after episode. SImply love it!! <3<3<3
