Brilliant drama, absolutely a gold medal winning series of 2017! It captured my heart right from the beginning and held the strong feelings inside right until the very last episode! It's one of those dramas that is filled with emotion. Showing the real and quite awful education system in South Korea, the realness factor was why I became interested in watching. Of course, I have to mention the other "School" series but unfortunately, I can't compare any them to this drama, since this is my first "School" series that I've watched. Nevertheless, the actors really put on a great show! As far as I know, the majority of them are amateurs in acting, I just have to give them cool points. Furthermore, the characters were relatable, totally "best friend" and "best couple" goals! After each and every episode, I had to tell my friends what kind of a great drama this is. Not only does it make you feel kinda cool, brave and happy after watching it, but also concerned and shocked about some of the school related things. To add, the music made a hugely positive impact. The OST is very fitting and there are a couple songs that piqued my interest. A wonderful drama for back to school or to reminisce the good old high school days. This drama will take you on a diverse emotion trip and leave you feeling chilled! Definitely re-watching it after I complete the other "School" series!
