Love the drama for the plotlines, overall good organization, sequencing and structuring of the main plot. The sub plots, although they are only a few , good enough to show the interconnection between characters and well supporting the main plot. In addition, I love the science behind the cardiorespiratory medicines displayed in this drama, the critical scenes in the OT - WOW, kudos to Yi Han and so Ji sub for mimicking the way a surgeon would behave!!!Further more, the procedures that they have showcased in the drama are OK and quite detailed, so good effort there!!! The pacing just nice and the plot logics are OK too. love to see the main villain and the main protagonists strategizing and counter - strategizing each other's plans. Lee Kyoung Young - wow - this person is really good in playing his role in depth . I really despised his demeanor in this drama !!!

Cast - wise, yes love to see the anti - hero - SSR - wow what a charismatic actor he is . Nice. Love the sense of ambiguity thrown into his character!!! You'd be wondering on which sides he is siding with though. The good or the bad guys??? which then lead to a question about WHO is he nd ultimately WHAT is his motive ? WOW. cool. Yuna Lim - - brilliant , a lady with a good sense of judgement and ethics, she is independent intellectually and emotionally brilliant - she judges every situations with her mind; not the heart even though we know who is her love interest is...the rest of the supporting casts are superb too.
Love the plot twist - it keeps me guessing WHO is having Seok Ju's heart from the get go - from one suspect of recipients to the next in each episodes hahaha . Apart from that , the plot is set up in such a way that I keep on wondering the' WHY 'or motive of one character, why does one character seem to harboring so much grudge against the main villain compared to the other , YEAH , their motives. Good narrative, and for those who love the medical sides of it, the drama is not boring though, if you really into it, the terms are OK. and I must say , they managed to water down some of the medical results and so on. I like the way So Ji Sub performing clinical examination on Yuna Lim and Sunae, wow, he looked very professional and like an experienced clinician - well he is an actor though , hahaha. Good medical advisor they have consulted here. yeah I love the issues they showcased in the drama - medico legal issues. cool idea. So , the drama is nice to watch and very enjoyable.
