The wittiness and playfulness of the characters intermixed with the heavy and intense main plot was done very well. It was one of those dramas that I started watching expecting to just skip through everything but ended up getting hooked and interested in the story. I hate Moon Chae won’s hairstyle so much but was surprisingly able to overcome that while watching it because she is an amazing actress. [FUTURE EDIT: lol girl what] The actors playing the villains did very well because they very much pissed me off with their evilness. Cha Ji won being one step ahead of the villains was very satisfying to watch but one could argue that they overplayed that card.
