I rarely write reviews unless I’m in the minority or I really, really agree. In this case it’s the former.

A couple of points to consider if you haven’t watched this drama and have read the reviews here (no spoilers):
- The relationship is set up from the start as problematic. That’s the point. Downscoring it for that is like downscoring a villain for being “unlikeable.” If you only like warm, comforting love stories, this is not the drama for you. Just like I’d recommend that you not watch horror dramas if you don't like to be scared.
- The folks saying there was no development of the characters missed some things. That’s all I can say without spoilers.
If there’s a theme to this drama, it’s about figuring out what you really want vs what your habits draw you toward. Lots of folks in this show make hard decisions in an effort to get closer to happiness. Is everyone 100% “fixed” in the end? No. But that’s also the nature of the ending… it is an ending for viewers, but what if you consider it a beginning for the characters?
BOTTOM LINE: This is a sexy, interesting drama that portrays complex characters and out-of-the-norm-for-kdrama relationships. If you’ve had bad relationships, you may not like it (tho I’ve dated someone similar to ML and loved to hate him for the first 2/3rds)—but this is the risk with any plot that reminds you of your past. The sdtk is great, it’s beautifully shot, and like that old relationship status, “it’s complicated.”
