Actually, from actually Korean History, this King is recorded by one of the Best Kings in Korean History, because he's the first King of Goreo(he is the founding father of the nation), and he's known as a wise king. But he is known for having so many wife, and dirty personal life. He's known as a Great King, but not a great human being. (This show's background is from real Korean History, the backgrounds are real, but the stories are fake)
