How I viewed this drama before I completed it and had only watched 8 episodes:
Original ranking:
Acting 8.5
Music 7.5
Rewatch 9.0
Overall 9.0

This drama is slow and medium-hearted. It depicts the life of the two main leads, who are fighting to make a name for themselves in a job they are passionate about. It is a drama that focuses on the real-life struggles of the leads, and the people that surround them. As a result of this, not everyone will find this drama interesting or enjoyable and that's okay.
Secondly, the acting by the cast is enjoyable and helped make the plot stand out a little bit more. As I watched the currently aired eight episodes, I did not feel uncomfortable by the way the actors chose to represent the characters, nor did I feel like one actor was outshining another, so I applaud the actors not only for their chemistry but for their ability to provide such a comfortable performance for myself as a viewer.

Thirdly, the script and plot so far, is it unique? 50/50. There are a few other dramas out there that depicted the struggles and life of someone in the entertainment industry, and the struggles of their female counterpart, however, the parts of this drama that do make this plot unique in my opinion, is the approach the writers have taken to touch upon the human aspects of some of these characters. In these types of shows, it isn't unrealistic to see the 'mean, rude, obnoxious' character(s) that constantly appear over and over and that constantly make the plot more generic. This drama does have obnoxious, rude characters, but thankfully it isn't the initial focus of the drama. Because the writer chose to focus on the humane aspects of the characters, we get a broader glimpse into the struggles these characters are going through, and rather than having them build up a facade for the public, they choose to continue to be as true to themselves as they possibly can.
Lastly. The way the overall plot is executed and the speed of the drama is slow but not too slow for my liking. Rather, I find it at just the right pace of not too fast nor too slow, to properly dive into the stories of the characters. Take note that as I stated, this is a humane drama about the struggles of the leads in their desired workplace, if the pace was too fast we would lose a majority of the plot and barely understand the key aspects of the overall story, let alone the relationships between characters wouldn't seem as genuine as they are at this moment in time. To sum it all up, I believe this drama is great for those who want to watch a nicely paced and humane drama, either as background noise or as something to just relax to.

How I viewed this drama after I completed it (UPDATED REVIEW):

I'm sorry but what the absolute hell was the writer(s) thinking? They completely lost their way the second half of the drama. The at first humble leads, who communicated quite thoroughly in the beginning, then changed and struggled to communicate and treated each other appallingly.
The various plot barriers (conflicts) thrown at them were quite lackluster as well, and the majority, if not all of them weren't needed!

I am absolutely astounded at how the writer(s) who had a perfectly somewhat realistic, and humane drama, in the beginning, could completely throw it all under a bus story-wise, and instead focus their resources in an attempt to 'cause drama and keep it entertaining' for views. As a result of their decision, the characters became really bland very quickly. Did the writer(s) even care for their characters?! As a writer myself (ie. Fanfiction and some original) I genuinely care about my characters and where they are going to end up, even if it's all fictional. Meanwhile, these writer(s) seemed to write willy nilly and destroy the original intent of the story. To summarise it all: I am severely disappointed.
