I was thinking a lot what to write about this drama. I've found the first 3-4 episodes very interesting, I even thought: wow, this is the best drama I have seen in the past few months. But then... Somehow it just turned out to be a bit weird, unrealistic and very rushed.
Even though I've liked the whole story and I gave good ratings (overall 8), I have the below comments about what I did not like at all:
- main female character: she cried a LOT! Also she fell for Dr Cha way too fast and then she tarted to chase and even stalk him which was very annoying. Also her hair was very weird (half short & half long?!)


SPOILER!!!
- crazy nurse: how come that she could be the nurse of her child's murderer? Very unrealistic.
- some story lines are just simply unfinished and had better potential: Dr Kang's guilt after her father's accident, her sister's and the other's doctor's love story, the secret organisation etc.
- some characters were poorly written
- last few episodes: what happened with Dr Cha's illness? He almost dies then suddenly he is fine. Also it's simply crazy for me that he has not contacted the girl for more than 3 years!! I mean seriously?! He supposed to be in love with her and he doesn't even text her for several years then she simply just forgives him.

Anyhow, as I said, I liked to drama because of Ji Sung being so charismatic. I've also liked to prosecutor. I liked the fact that it was about a sensitive topic such as euthanasia, but even that part was very confusing.
