Upon hearing so many positive reviews and remarks about this drama, the craze has gotten into me as well. I decided to binge-watch this during my mandatory quarantine. It was very difficult to get into the drama right at the very beginning - the plot seemed too thick to debunk. There was a shroud of mystery surrounding the characters, which was intriguing, but together very complex and required complete concentration to realise the whole plot. The story seemed very underrated and very unlike the traditional cheesy Kdrama. It tackles themes such as mental illness, murder, friendships, romance, childhood trauma and so much more. To be honest, it can be a handful to handle for a beginner watcher. However, the cast is very talented, just as expected from Kdrama veterans, which were perfectly chosen to act for this difficult series. I believe that the characters and the acting is what made this drama spectacular and completely unforgettable. Not to mention the gorgeous sets and beautiful outfits. You cannot disagree that Ko Moon Young is definitely a Kdrama style icon of 2020. In addition, the soundtrack was very fitting, with a mix of Korean ballads and English songs. Personally, I could not rate this a 10 as it was lacking clarity and was not that captivating at the start: I only got into the series as it was progressing. But I will not forget the chemistry and the acting of this drama. Overall, this series is definitely a new concept and I can see the praise behind it. If you are into deeper, heart wrenching and a bit disturbing themes and plots, I feel like you will enjoy this a lot!
