This drama had the whole package for me personally.This drama in my opinion was excellent but with a few errors. I couldn't belive when I first watched it how similar my life was with the main character(not the rich thing though:D). She has an autistic younger brother like myself so she is very helpful to him. I realised that this had to be believable and it really was. The autistic boys acting was spot on and she really did care for him thorughout the story. But anyways back to the drama.The drama was fresh for me as I've never seen a drama with so many elements to it.It is very complex at times and you find yourself stuck to your computer screen. The acting is incredible and the way the bad girl(Moon Chae Won)is able to act so innocent and so evil at the same time is really incredible.A few flaws with it is the length although time passes quickly in the drama you may find yourself a few times screaming at a character to think for a second. But overall it isn't boring.And finally the chemistry between Han Hyo Joo and Lee Seung Ki is brilliant. I would definetly give this drama a ten out of ten and reccommend it for everyone!!
