Masquerade (Korean 2012)- Lee Byeong Heon! Plays the king in this "prince and the pauper" tale. This looks interesting, I like stories about kings who were considered cruel, but could have just been being the "bad guy" for the benefit of the country; Best kind of martyr (don't actually know if thats what this is about XD)
Currently watching Yi san (이산), a Korean historical drama set in the Joseon Dynasty. Lots of politics in the royal family. There's also a love story with the Crown Prince and palace artist, his childhood friend.
