[Watch this if you like series that are adult and women-centric and highlight their struggles without demeaning them.]

This could very well have been a soap opera with only entertainment value and nothing to take from. It is all in the characters, the situations and the commentary on relationships: how incredibly human all these women (something you don't commonly witness happening on television) and men were, how real their struggles were within their workplace (especially for women), and how incredibly vulnerable relationships are.

When it comes to the plot, you could boil it down to a marriage that starts to fall apart when it is discovered that the husband had been unfaithful at one point, with workplace politics thrown in the mix. However, the execution is what matters, and that was done wonderfully. The process of the trust and marriage breaking down was very authentic to life. Na Sung Jun went through different phases as she tried to come to terms with her new reality, and those were painful to watch. She acted unlike her past convictions once she was thrust into a conflicting, heart-wrenching situation where she is left questioning everything, from people she knew to herself. The writer fleshed out her emotional struggle so realistically it was frightening - one day, she is thinking she wants out; the next day, she wants to stay married because she cannot allow her marriage to crumble; then the next, she wants out; then the next, she wants to inflict misery upon everyone, including herself. Park Sung Joon is a man who is desperate, insisting on continuing the marriage, until he accepts that the trust is broken beyond repair, and acts in more hurtful ways in his confusion (which cannot be justified). We are also shown how lack of communication and presumptions in a relationship can be damaging. All sides of the story are told: the hurt woman, the remorseful husband, and the mistress (who is more than that).

I want to point out that Park Sung Joon was written amazingly in that his story is powerful and dreadful in its truth. He reminds the viewer that the act of unfaithfulness is not a symptom that reinforces how much of a jerk the cheater is, but a path (albeit highly immoral) that a good person can also choose, in an effort to counter the torment of self-inadequacy and threat of never being accepted if their rough edges come to light; it is a part of a series of decisions they make that end up leading them to a point they can never redeem themself from. His upbringing provides insight into how an adult with personal reservations so strong can be created that even their healthy relationship makes a dark, hidden part of them feel unsafe. The writer maintains a balance in that they make you feel sorry for yet angry at him, because his insecurities and presumptions were, after all, only in his head, if only amplified (and that is what we all fall prey to, so this is why it is so scary). Not only him, but the other party were also written in a human way: an everyday person, in their search for validation and understanding, making equally unjustifiable decisions.

However, the drama is not only about them. It is about womanhood, and so we are introduced to the stories of other women. The most notable were Lee Hyun Ah and Song Mi Na. Lee Hyun Ah breaks all stereotypes surrounding self-made, confident, proud women. Yes, she walks with a straight back, and has intimidating class, but she is also a woman with principles, a good heart, and her own pains, even when they are not apparent. Then there is Song Mi Na, a woman torn between her duties towards her family and her ambitions as an individual. I personally found Mi Na’s story really moving and something many family-oriented and ambitious women can relate to.

Aside from that, the writer did not label every thing as black and white. For example, emotions such as envy and jealousy were depicted in a very normal light, something anyone, even a good person, experiences. The main characters make irrational and imperfect decisions at many points, but they redeem themselves from that point and develop themselves. Of course, those who failed to fulfill the latter were criticized (Ohn Yoo Ri and Park Sung Joon).

I do have a criticism: the writer creates some situations but never follows through with them. It is a character-driven drama, so it was expected. However, I think there were occasions the writer could have built upon.

The drama could have fallen apart had the scene sequencing not been so good. The narration was spot on precisely because of the decision to withhold exploring a scene completely, piecing some events together in a way they looked true but, as the scenes are properly delved into, show how the viewers were misled deliberately. When it comes to the cinematography and the like, my favourite thing was the little nuances that the camera work caught and the director included. They were not always made obvious, but you caught them if you were present throughout the episode. It could be one or another woman’s doubts about herself, maybe her envy for the other, or some character's lingering emotion, or something more simple. It prevented things from being dramatized and maintained the natural element and its significance. Moreover, the music complemented the scenes well - one of the reasons I looked forward to this drama; the instrumental was well done!

Now the acting: amazing. Jang Na-Ra delivered, like she always does; she was cold, miserable, strong, warm, graceful, all at once. Lee Sang Yoon did not have a lot of freedom to share his emotional range, because Park Sung Joon was a stoic man, but he was very convincing for a man who was consistently battling internally yet his internalized beliefs about himself prevented him from expressing his feelings; him and Jang Na-Ra convinced me they were a couple of ten years that was falling apart. Lee Chung-Ah was amazing in her role - I cannot imagine someone else pulling off Hyun Ah. Shin Jae Ha has great timing with his expressions, and very natural with them - you could see his growth from one half to the next of the drama as well. Kwak Sun Young made Song Mi Na’s ambitions and conflicts come to life. Pyo Ye Jin was great in her delivery of a confused, insecure, and self-victimized person. For the side characters, I want to mention Lee Jae Won (Byung Hun) - he had great chemistry with Kwak Sun Young and was great at forming an intimacy with her of a married couple.

This was a very thought-provoking show about relationships, with yourself and others. A must-watch.
