The plot is nothing crazy (as of Ep 6) and we've seen these tropes before. What makes the drama unbearable is the acting. It was quite in your face, nothing sutble or refined. The cinematography and the cuts were all very old-fashioned/amateurish. This was my second attempt to give it a fair chance and power through, but ultimately what turned me away was the execution. FL is supposed to be an OP (or at least somewhat powerful) character since she hails from a general's family. For some reason, her schemes and acting as a playboy aren't up to par. She's found out by two important characters about 3-4 episodes in. One of them found out because she was wearing perfume (?). This is the screenwriter's mistake, but the actress that plays FL made really exagerated expressions when she was questioned. If she cannot maintain her composure, then how are we to believe that she's supposed to fool the Capital into thinking she's her brother.

All in all, even if I had the spare time, I would not try to push through this drama and try watching something else.
