You don't know how many times I've rewatched this drama. I LOOOOVE IT SO MUCH!

Looking at the reviews from others are quite diverse. Some are loving the first season, the others love the second season. These kinds of different opinions indicate that this series did it right. I think it depends on each preference and that's totally okay. I loved the second season more.

The reasons why I loved the second season sooo much, even declaring it as my lifetime drama are because of these reasons:
1. It's really beautifully written. The story flows really well. Every episode leaves you on the edge of your seat. Nobody is perfect (except Kim Sabu ofc). They have their own struggles like everyone else in real life and the character development makes us rooted for them. I bawled my eyes out for some episodes and I'm someone who rarely cries while watching a drama. It's very inspiring and makes me look back on how I am as a person. I want my own Kim Sabu too...
2. It focuses more on the hospital and medical aspects than the romance part. Many medical dramas are just romance drama with a hospital as a background or doctor as an occupation. I found the first season focus on romance more too. Here, they prioritize their job as a doctor first, to save life first. But they also showcased how doctors are human too. The cases are very very interesting. I even rewatched the surgery scenes only just because I admire them sooo much.
3. The acting. Gosh. At first, I found Cha Eunjae character annoying and started to doubt Lee Sungkyung acting. But as the episode goes, she got better. I understand her better. I sympathized with her character. I think it's a success for Lee Sungkyung. No words are needed for Han Suk-kyu, he deserves all daesangs in the world. Ahn Hyoseop, God... How come he's very good at acting yet SO HANDSOME?!?! In fact, I became his fan and watched almost all his filmography after watching this drama. And other casts too. I really could believe that they are real people, not an actor. They did such a fantastic job.
4. THE CHEMISTRY! I loveee all the Doldam Squad. They are really like a family. I also love how the mentor relationship between Kim Sabu-Woojin and Kim Sabu-Eunjae unfolds. I think their chemistry is better than S1. Well again, Kim Sabu became much softer in S2. And for Woojin-Eunjae, wow. How come they have such overflowing chemistry by only exchanging gaze??? They speak with their eyes... They have a very minimal romance scene, but it's very beautiful. The best slow-burn romance story for me. It's frustrating but understandable? Like I totally understand why Woojin hesitates a lot and Eunjae needs time. Anyway, it's really rare even in real life to fall in love quickly with someone right?
5. The cinematography and the OST are gorgeous. I could feel that the director, writer, and production team really love and have pride in their works. I applaud them soo much for making such a difficult work beautifully. Excellently executed.
6. I am obsessed with their epilogue with the college story of Woojin-Eunjae. I really wished they made a prequel or special episode for their college days only :((

I dislike any slander for my lifetime drama. But again, everyone has their own opinion. Hope you give it a try, and I hope you like it as much as I do.
