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
Killer Ex husband: His acting is outstanding. Character is more complex than the ML.

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!

Ending..... UGHHHH honestly the last episode was NOT needed. Did they REALLY need to send ML away for yet another battle? Really could've ended before that.
