What to say more that has already been said about this drama.
I completely enjoyed it and was really into the storyline.
The acting was immense and carried the plot. I always never enjoy Hyun Bin in the first episodes of his series for some reason but I always end up convinced just by his acting. I am impressed by his acting skills, I remember watching Secret Garden and not be that appealed by his looks but ending up liking him overall by the end of the series and enjoying his visuals more and more - hands up to that!

Great rewatch value also, I plan on rewatching it whenever running out of good dramas to explore. :)
I also liked the balanced ending which I believe a lot of dramas lack lately.
