I finished watching this drama within a month since I was so attached to it I couldn't stop watching. The plotline is so gold. It criticizes the system of teaching and how families would do anything in order to keep their reputation and improve their children's education. I personally could relate to this drama very much since I too am a student who just recently submitted their applications. The stress over rankings, grades, maintaining my reputation, and ofcourse, the multiple tests you have to take are all incredibly real to me. The casts were amazing. There's no one else who would do a better job. This drama does an incredibly great job of evoking my emotions of anger, sadness, empathy, hate, as well as humor. I am glad this drama is one that has so much to take away from. I highly recommend Sky Castle to viewers of any age range. (Also remember to prepare some tissues I sob in like every episode it just really hits home for me.)
