I would say this drama was OK. I mean it started on very interesting note but in the middle i lost interest because it become kinda boring.
The main lead doesn't have good chemistry as lead male and 2nd lead female has and 1st female lead just become annoying.
They sacrificed good character development just for the plot which somewhat seam forced in the end.
I was worried for the patients because doctors were just looking and taking with each other while in operation room.
Lee Jong‑suk and Kang So‑ra had interesting character and good chemistry.
And the ending is not that good. they had the chance to make plot more interesting but they ruined it.
