This drama absolutely blew me away, the psychological aspect was just amazing! It was not very predictable and always had me trying to guess what would happen next. I love it when shows have me involved and trying to guess what will happen. It completely had me pulled in, I didn't want to put it down (I had to because I started watching it really late though). The story is not one you see everyday as well and I am sad that I haven't come across a drama like this before. The acting was extremely professional, I am happy with the actors performance. In the drama you see how all the characters begin to change and see sides of them you didn't know they had. I really enjoyed the music but I would like to know why Brittney spears song 'Toxic' was the ending theme. I did not understand that at all and it really didn't fit... I might rewatch this in the future just to experience it all over again. This is now one of my favorite dramas, and if you give it a chance, it might become one of yours as well.
