okay so i personally never got the internet to start a medical drama but somehow I started dr. romantic on yt. and oh. my. god. i good hooked to the plot so fast. I believe Season 1 was more focused on the medical theme and season 2 had more politics added than S1. i was kinda bumped that the couple from S1 was not in S2. but after finishing S3 i came to understand the "bigger picture" of the whole dr. romantic world. hoping for one last season 4 with the cast of S1 n S2 together. (side note: S3 was WAYY INTENSE in the happenings comparatively)
now talking about the characters. I LOVE MASTER KIM SM!! he's legit my no. 1 fav kdrama character ever. He's a talented,charismatic leader. I loved his small jokes and smile. Also master kim had such a good relationship with all his junior doctors. SUCH. A. COOL. CHARACTER. Each and every doldam staff was so likable (esp. Mr. goo and head nurse)
.
ROMANCE was up to the mark since the main genre was not romance. they storyline was perfect.
.
As I progressed watching the show from S1 to S2 and 3 I built like an emotional attachment with doldam hospital and it's people.

!! ONE BIG REQUEST TO PPL THINKING TO START THIS SERIES !!
.
please PLEASE DO. NOT. start S2 first and then others. I urge you to watch from the beginning. S1 was really good (kinda better than S2 in my opinion). You won't be able to enjoy S2 more if u don't know the background of S1.
