This drama is a reflection of a big problem in our society, bullying., it shows the cruelty behind the issues of bullying in Korea. This is the second Song Hye Kyo drama I watched, it made me fall in love with her again. Everything is perfect, the drama is very interesting from the first episode. It made me feel the pain and anger she felt when her classmates tortured her to hell. It also made me feel very good when she was slowly reaching her glory. Here she shows that she is a master of interpretation.
