First I would like to clarify I got into season 2 without watching s1 and because ahn hyo seop was playing….

I was hooked from episode 1 and invested throughout the series, the end even left me wanting for more which I can’t believe my luck since s3 just started airing (As of writing this)
The writing was surprisingly better than I expected, the drama aspect outside of one/two moments was well balanced, which was also surprising~ I expected it as a medical drama to be even more over the top.

Characters were definitely the highlight of the series for me
Woojin (Ahn Hyo seop‘s character) I instantly liked from minute one and Eunjae was also likeable.
((Insert rant here: I saw way too many comments about her being annoying which I honestly do not understand??? I feel like there are way more actual annoying main female characters out there but of course hating on the female character for being weak or having a mental problem is quite common.))
Moving on Master Kim was also good! Loved him as the mentor character especially with woojin.

The other side characters were also good and I did not find boring for once, from the main nurse and manager to the other doctors and the cute side couple.
The bad characters although extremely annoying didn’t seem unreasonable or too cartoonish (at least to me). Some even had their development by the end like park for example.

I understand if romance was the only reason someone watched the series they could come out disappointed as it was not that much the focus. Personally I did not feel the series missed anything in the romance department and that is because I liked the mains dynamic and found their interactions enjoyable. Sometimes a simple romance works better than a drama filled and complicated one which was the case here!!

Overall this is definitely worth a watch!!
I also recommend starting with season 2 and if you are invested enough go back for season 1 as I did myself,,, since in my opinion s2 is much better than s1
