The lead actress as my title suggests, is the pièce maîtresse of this show. Her acting is awesome not once did she fall into the basic "cold demeanour" act the role would have led many actresses into. I've seen it so often when an actress has to play a cunning/ambitious character they tend to fall for the cold-blooded stereotypes and it often end up feeling a bit caricaturist...here, she didn't. She managed something fascinating that I will refer to as lukewarm for lack of a better term. I was truly intrigued and fascinated. She managed to be appear distinguished, witty and levelheaded yet pitifully weak and distasteful. But all the while inciting warmth. This is a case in which the main character REALLY is THE MAIN CHARACTER. She carried this whole thing on her back.

The sidepiece she succumbed to was cute. I liked him but he had the tendency to overdo the "borderline autistic" act which was cringey at times. However I really liked his naivety.
The whole dynamic within the wealthy family felt alien to me. I just couldn't understand the motivation behind so many of their actions...it made little sense and seemed to just serve the as a way to give the illusion that everything was more dramatic and complicated because of how lacking the scenario was.
The supporting cast in this fell flat. Usually, the supporting cast adds value to a drama and in some cases saves it but here it was pretty much the opposite. I only cared for the the main actress's storyline.
Nonetheless I still found enjoyment watching it. The fact that I like piano in general probably helped. Could have done with less slowmo during the piano lessons/showcases but really what do I know about cinematography?

Most dramas, even those that I absolutely love, have anywhere from terribly disappointing to so-so endings. This one breaks from that pattern. I liked the ending and felt content with it.

Side note concerning the woman playing the main character:
When I look at her face there's something within me that feels unusual.
l haven't managed to put into words. It's a weird emotion that makes me uneasy and slightly sad. I felt that way watching A Wife's Credentials and not because of the storyline or the unfortunate events the character she played went through. It's just her face and the aura around her. I don't know if anyone else feels that way but I do.

I want to grant the main actress a 10/10 but since I can't rate her separately, it's frustrating but I will give the acting/cast a 6 at most.
