I loved this drama so much. It's realistic in that no one is portrayed as a villain nor a hero. It acknowledges the injustices in the world and tries to depict several realities and personalities. It is a drama that covered several bases as I was just as invested in the game plot as I was in the backstories of the characters. There were definitely a few plot lines that were left unresolved but apart from that, the story, visuals, and acting were all superb. Definitely a great drama for non k-drama fans, as seen by the worldwide craze.
