This was a really cute drama that I liked much more than I expected to. I avoided watching it for a while because I'm not a big fan of hospital dramas, so it has been on my "plan to watch list" for a long time. I'm also not a huge fan of divorce plots, since divorce isn't such a stigma where I am from, so the shame of divorce gets really old for me quick. Despite these two things, what kept me watching was the romance. The romance may be cliché, but it is done well. That has a lot to do with the cast. It took a little while for Choi Jin Hyuk and Song Ji Hyo to grow on me, but once they did I loved their banter and chemistry. Like most divorce plots, there is a lot of pettiness, jealousy, and bickering, with some cute moments thrown in too. There's also a healthy dose of second lead syndrome thanks to Lee Pil Mo, who I totally empathized with and rooted for. Then Choi Yeo Jin adds to this great love triangle while not playing into the stereotypical role that's expected, and being the most likable of the four for me. The supporting cast is great too. The emergency room staff was entertaining, and had interesting backstories and plots of their own. The patient stories also weren't too annoying, which it my pet peeve with these type of dramas. Some situations were a little over the top, but most were interesting, and I liked watching the characters work through solving the emergencies they were faced with, especially with their personal tension. However, even with all of this, the plot is super basic, and I just couldn't give it more than a mediocre score. This drama is long, 21 episodes, and although I was never bored, the story didn't really justify that many episodes. One thing that I did hate was how things were so drawn out, and how many flashbacks happened in every single episode. A scene would end and then literally repeat, or the same scene would be repeated over and over again. It felt a little like deja vu while watching. Then literal actions would seem to happen in slow motion, and maybe that was a choice to add to the suspense of the moment, but it just felt like a way to waste time. Also beware of fantasy scenes, some were hilarious, but they also felt like time fillers. The music was Ok, but I can barely remember any of the songs, which isn't a good sign. Overall I'm glad I finally watched this drama, and it was an easy one to binge through while waiting for currently airing dramas to air new episode (watching took me about 4 days... so perfect!). The rewatch score is pretty high, because of the characters, but I doubt I would watch it so many times like others have claimed. At the end I really felt like I went on a journey with these characters, and the ending was a nice way of implying what would happen in the future without feeling like a sequel was necessary, or that things were left unresolved. I would definitely recommend this as a binge-worthy rom com, that exceeded my expectations. If it's been lingering on your plan to watch list too, maybe it's time to finally upgrade it to "currently watching".
