_____Story_____
Pros: The plot was unique, and so were the characters. The portrayal of people's internal conflicts astounded me. Ae Jin was so helpless at school that she pretended to be someone other than herself most of the time. She found pleasure in her second identity that she couldn't find in herself. The plot moved quickly, and the way things were revealed was intriguing.
Cons: The beginning was a lot of fun, but by the time we got to the middle, the drama had sunk. I won't say why because doing so would be a spoiler.
I really liked the idea that this drama was attempting to convey.

______Acting_____
Shim Dal Gi (Koo Ae Jin) and Choi Bo Min performed admirably (Kim Ho In). Dal Gi's performance as Ae Jin was superb, and Bo Min was successful in giving Ho In a psycho yet attractive vibe. He made a favourable first impression on me, and I was encouraged to watch his other dramas. The one flaw in Dal Gi's acting was that she exaggerated her performance. But, at times, I felt it was necessary because she was behaving like a mentally ill person.

_____Rewatch Value_____
The main reason why the rewatch value for this drama is high is because of the amount of episodes and its duration.

______Overall______
Shadow Beauty is neither a good nor a bad web series on the whole. This drama has its own set of weak and strong points. Some may enjoy it, while others may not. It all depends on how you look at it. Personally, I enjoyed it. I won't say it's a must-watch, but it's definitely worth watching, and I recommend it to everyone who reads this.
