And I love it! Yes, the story as a whole has a different development, this being more "daily life" rather than a plot with start, climax and ending. While DotS is more like a very long movie, this is more slow paced, and more relationship-centered.
What is VERY similar are the main characters descriptions: a talented female doctor and a young but successful special forces male.
Overall I feel they each have their strong points. For the chinese series, you get to see their feelings grow and their relationship feels more real. Perhaps you'll get tired of it (unless you're already used to chinese dramas), but I'm pretty satisfied. The actors are good and charismatic, the story shows a lot of the medical part without being boring and in the end we get what we always look for in chinese dramas: couples being so freaking ADORABLE.
The biggest flaw for me is the side couple... girl, you should listen to some BTS and love yourself a little (or a lot) more.
