I am so on the fence about this drama. It had such a strong start with a number of different moving storylines. Yet, I feel like all these story lines kinda trickled out. Even so the majority of the leads did an excellent job. Lee Jong Suk had probably one of the most compelling performances even compared to his roles in W and Pinocchio. His depiction of the lead makes his character very likable and touching in parts. Both Park Hae Jin and Kang So Ra had very notable performances too. I have to say the weakest part of this drama has to be Jin Se Yeon's character. I'm not sure if it's a flaw in the writing or just Jin's acting ability. I think from the beginning of the drama the audience is supposed to question Jin's intentions, but the drama is never able to aptly prove to the audience that they are seeing her genuine feelings ever. So Lee's dedication and love for a character most of the viewership can't trust becomes this drama's fatal flaw. I think this drama missed the mark in the later episodes. I do still think Lee Jong Suk and Park Hae Jin fans should still see this drama, just prepare yourself.
