The recycled revenge drama script continues to be the trend. It's one of the better ones though at as the production quality is very nice. It gives off a darker vibe with vibrant colors. Make up / costume design especially unique. Lots more dark reds right down to the makeup & wardrobe of the ML. Compared to a similar drama like Story of Kunning Palace I think this drama did a better job in terms of storytelling, casting, & production. So even if the script is nothing new, and lots of unbelievable scenes, it's still a great watch!

FL/ML pairing works nicely IMO. Both are equally mysterious and calculating. The acting's convincing especially the FL's crying scenes.
FL : I am not familiar with her prior works, but dancer background brings that special grace that non dancer background actors can't fake.
ML: I watched some of his prior works and he can act but in terms of characters, this character is the most interesting thus far

Slow romance:
Their encounters were not overly forced, and the development of the relationship is slowly brewing which I am enjoying. Ep 9 on the leads finally starts to have more interactions. The chemistry becomes more evident in ep 11!
