For me, there are seasons for certain types of shows. My main focus is romance with the much-needed HEA. That being said, sometimes you need a slice-of-life show where you come to know and love the characters, and this was perfect, I must say. I really liked season 1 a lot, but season 2 is on another level. We already know how close all the characters are, and it was so enjoyable to learn and grow in their relationships with each other and those outside their little circle of friends. Extremely well-written and with well-rounded characters, I watched this in three evenings. There were undercurrents of romance for each of the characters and it was refreshing to see mature relationships, with nary a stupid breakup in sight (Jun Wan and GF are somewhat of an exception, but I'll forgive that). I could go on and on about this show, but I'll just give a couple of my highlights.

Jung Kyung Ho as Jun Wan - love his knowledge as well as his sometimes immaturity. One thing I found fascinating about him, did he lose weight for this role? He was SO thin and I just kept thinking that because of how busy he was he didn't have time to eat. Granted he's a small-boned man, but he can sure wear his clothes! And in scrubs, his "thinness" is really obvious. It was a good look for him.

Bromance between all the main characters. They had each other's backs but weren't above wrestling for the remote control!

Kim Hae Sook as Rosa (Jung Won's mother). I love her in anything she is in, and her character, as well as her storyline were wonderful. It's refreshing to see a mature person in a good story.

The love/hate relationship between Jun Wan and Jae Hak. There was something kind of stalker-ish about Jae Hak, which brought a lot of humor to the show, as well as their relationship. I also loved the storyline of Jae Hak and his wife.

Jun Wan and Song Hwa are the piggies of the group, constantly eating more than their weight in food. They thought about food, talked about food, and planned what they would eat next.

Sung Hwa as a bad singer. This was so cute to watch and hear, especially since she has such a lovely singing voice.

All the music. I REALLY appreciated that they said what the songs were and who was performing them. I also liked that the actors did a lot of the music.

The medical aspect of the show was often heart wrenching, but it was more about the characters than the medicine.

*If I had to voice one complaint, it would be that, as a health care worker, the first thing we learn is how to talk to patients, compared to other medical staff. The doctors in this show often used medical jargon that no layman would be able to understand. But, that's just a slight blip in an otherwise stellar show.
