Okay. So I originally dropped this drama months and months ago because the first episode was just too over-the-top for me, which didn't appeal to me. Song Yi in the first couple of episodes was pretty intolerable because she was so arrogant and such an airhead, but as the story progressed, her character changed in realistic ways and she was likable by the end.
The story's plot really thickens around episodes 4-6 and that's when I finally got hooked and wanted to binge watch it as much as I could. Aside from the twisted plot that intrigued me, I also liked how Min Jun reminded me of Superman in many ways. I also felt that Jae Kyung and Min Jun were pretty well matched foes and so watching them struggling against each other had me on the edge of my seat.

I did almost, for a split second, have second lead syndrome because Hui Kyung was just so sweet and tender with Song Yi, so I was swayed during a couple of scenarios. But then I remembered and was reminded how Song Yi and Min Jun needed to be together, sooooooo yeah, I stayed on my ship XP

The most heart wrenching things for me were Hui Kyung and his family discovering the truth behind his older brother's death. I truly cried for Hui Kyung and his father.

I think the ending was pretty good, but I kinda wanted an even better ending; the ending is truly happy, but I just wanted a more "happily ever after" ending (you'll understand when you watch). For me, Song Yi and Min Jun went through so much hardship together, I just wanted things to end *perfectly* with no caveats.

This was my first drama with Kim Soo Hyun and I thoroughly enjoyed his acting. His little outbursts when Song Yi was just getting on his last nerve were so adorable. His crying was pretty well done too. I think I preferred Jun Ji Hyun in Legend of the Blue Sea, especially since I think her crying scenes were better in LotBS than in YWCftS, but that's just my personal opinion.
Park Hae Jin was probably my favorite actor in this entire drama because he portrayed Hui Kyung in such a raw manner that I couldn't help but love him and cry for him.

The soundtrack was well placed and appropriate, but not anything that I'm dying to relisten to.

Overall, I'm glad I decided to pick this back up because I really did love it. It's not one of my top favorites, but it's definitely something I would recommend to others, especially to those who enjoy Superman (he's my favorite superhero personally :)).

***As a complete side note that didn't impact my rating, but just something I noticed being in the medical field --- every time someone had a surgery or some kind of extreme injury, they recovered or healed or bounced back way to quickly in unrealistic ways. For example, Song Yi has at least 2 major abdominal surgeries in the entire drama and within days they show her sitting up on her own without wincing or crying out, implying that she feels no pain from the very recent surgery incision....which simply wouldn't happen because she literally had SURGERY - it wasn't just a scratch! I think to make the screen writing a bit more flawless, having more care with those scenes would have made it an even better drama.
