I was captivated at the beginning. Then, like a lot of other K-dramas — it became too makjang-y and fell flat towards the end. I would say the acting carried such flawed storytelling all the way to the finish line. Kim Ji Won and Kim Soo Hyun are fantastic actors. The supporting cast does not disappoint as well. I'm still miffed at the wasted potential of the story, though. I think I felt totally disconnected from it by episode 13 and only continued watching because well, I was just 3 episodes away from the end. OST is great and hits you at the right moments. No rewatch value for me as I found the storyline too frustrating with a lot of elements that it could really have done without, especially in the last few episodes.
