I loved this drama. It had everything; love, hate, fear, death. I was extrememly interested in the psychology aspect of the drama as I am a psych major. I gave it all 10's b/c the story was amazing, the acting was perfect, the music was awesome (had a lot of songs that I listen to), and it overall messed so well that I will watch this over and over. I have recomended this drama to my friends at work and will to any1 else that I know. I loved the concept that was born and how it all played out. A wounderful question that I have myself been trying to answer since I work in behavioral mental health. Whomever thought this up has a very analytical mind and knows how to go beyond the boundries set for experiments in the psych field. It is a very fine line that can be crossed at anytime. I probably like this more because it is based on a topic that I am interested in anyway. It kept me on the edge of my seat the whole time.
