The talk about a woman disguising as a man in a Korean drama, is a tale as old as time. I don't think there's anything to get irritated about, because if you have been watching movies, TV series for a long time, be it any country you must have seen such blunders where we all can distinguish the woman as a man and only the male protagonist and others in the movie stays oblivious. Thus, I'm really not worrying about this thing here. The female lead lacks in acting skill, for sure. She's just staring a lot and has no proper expression. Additionally, her cause of taking revenge on Jin Han is entirely baseless. The only reason I'm watching the drama is for Jo Jung Suk, also the plot intrigues me because I like political drama be it Korean or Chinese (Chinese political historical drama are the best). All I hope to have a happy ending, and no open one.
