For me, this is the best kdrama I've ever watched not only because the storyline is great but everything from the actors and actresses, soundtrack, screenplay, etc. was absolutely amazing and fresh. Sooo good that I actually watch it over and over until I can move on from the ending of the show. Kim Go-Eun blew me away with her performance. She totally crushed my heart in episode 10 with that heart-wrenching ending. Her chemistry with Lee Min Ho was, unexpectedly, the best so far. Very satisfying finale. Highly recommended.
