This drama has everything in the right dose. I'm in love with so many aspects of this drama that the pros do outweigh the cons.

OST:-
THEY NEED TO BE ON SPOTIFY. THEY ARE AMAZING. I LOVE THE SONGS.

Acting: -
||Pros||
Both the leads and the side characters are relatively new to acting but all of them did an amazing job. The side characters are pretty good. Even the guy playing the villain has his comic relief moments which are genuinely hilarious.
||Cons||
The male lead needs to work on frowning less sometimes and the female lead needs to work on smiling less sometimes, but these are not something that can hinder your experience. Just remind you that they are inexperienced.

Story line:-
||Pros||
Here is where I have to disagree with a lot of people. Many people complain about how contemporary modern c-dramas don't get the essence of the setting that the characters are put into. But in this case, the writer stayed true to the setting from the beginning till the end. I learned so much about how the clothing, fashion and manufacturing factories work. Like the content of the dialogues and the proceeding of the events are something that truly does happen in the business world. And it's a nice way to learn something new.
{Disclaimer: I am not a business person and have never done anything more business-y then statistics and general economics. The contents seem legitimate based on my limited research]
||Cons||
For some people the information about the ways companies run can be an overload of information.
The writer also resorted to take ideas from a variety of plot lines that are quite noticeable (though well mashed up and it doesn't lose pace). Especially, the beginning of the drama is very similar to the beginning of a South Indian and its adapted Bollywood movie, Ghajini.

Romance/Chemistry:-
||Pros||
The lead couple had an amazing chemistry on-screen. From the first episode when Luo Tian Yi walks into Chu Chu's office, and the way he was looking at her, I was a goner. AND THEY DO KISS. [Disclaimer: Not Western style but they aren't statues either. Somewhere in between.]
||Cons||
Their chemistry is too fatal to my heart.

Character/Character development:-
||Pros||
This is where the show gives me the cherry on the top of this already well endowed cake.
The lead couple not only has an amazing chemistry but also a HEALTHY & MATURE RELATIONSHIP. Can you believe a c-drama having that? This is the second time after Love O2O that I have seen such a couple. However, I would claim that this couple is much better due to other aspects. They RESPECT each other and give each other the FREEDOM to do what is right for their career. No one is "unnecessarily jealous" to show that they "care and are in love".
This show deals with a few sexist and discriminating side characters (Luo Tian Yi's extended family), but they deal with the issue quite well, letting Luo Tian Yi's character be such a reassuring person and supporting Chu Chu even through his hormone. [Disclaimer: Some would say that is what he is supposed to do, and I agree but how often do you see a c-drama lead who is not overbearing, obsessive and forceful... NEVER!!!]. He gives Chu Chu his wholehearted support for what she wants to do for her career and fights any evils coming her way with her. Not for her, but with her. And when time comes and he needs help and support, she helps him too. A very WELL-RESPECTING and BALANCED couple.
||Cons||
Of course the sexist comments would leave a sour taste in your mouth. And the story has a very frustrating, manipulative, but comic and stupid villain who helps the story line progress so beware... He is gonna stay till the end.

BEST CHARACTER: Chu Chu's Mom, Luo Tian Yi
WORST CHARACTER: Luo Tian Yi's Uncle.

Overall:-

I would love to watch other works from these actors and actresses. They have talent and visual. The story line progressed at an intermediate pace which was never frustrating or annoying in any way.
