Ever since I finished the drama School 2017, I really wanted to get into watching all of the earlier versions. I started with this one.

School series in particular have this specific way to delve deeply into the problems of South Korean students. Who Are You: School 2015 was based on bullying and common family problems. Also, this version offered a lot of mystery elements which I really enjoyed. Sometimes it felt like you were reading a crime novel!
The storyline was quite hard to follow, especially in the first episode, but the eventually everything started to fall into place. I get why a lot of people like to be harsh critics of School 2015 (probably the second lead syndrome that everyone has gone through). Yes yes, there were so beautiful moments portrayed by the skillful actors, whom I already recognize from the previous drama that they've starred in. Some characters in particular made me mad and sappy, happy and sentimental. My emotions were all over the place and I guess it's supposed to be the main objective of the drama.
The OST was touching and enjoyed as well. Can't help but replay all of the songs after watching it!

If you're into school themed dramas that deal with teen problems and first love, this is the drama for you! The storyline is gripping, the actors are superb and the music will definitely enchant you!
