I absolutely loved this drama. Hyun Bin did a tremendous job protraying two characters so convincingly different from eachother. I enjoyed how complex and yet so simply everything about split personality was handled. I liked the ending too. The love story was beautiful. The story gripped me from the get go. It was paced good till episode ten, then slows down a bit from there on, but at no point do we lose interest in it. Infact, it becomes more engrossing because by then our emotions are already involved. I wanted to know how this is going to affect the lives of the characters and what will they have in the end.
Great Work from everyone, especially Hyun Bin !
