This is not the first K Drama i have seen, but it certainly left a long lasting impression. The plot is absolutely simple with very believable characters. It has been very tastfully made and the emotional struggles are captures without any over the top acting. Some may find the pace slow, and it does loose a bit of steam in the middle but it does recover towards the end. Park Bo-gum and Song Hye-kyo played their parts brilliantly. The subtle soundtrack compliments visuals beautifully all along. Overall it is well worth watching and i did enjoy it. Being a Song Hye-kyo fan, it gets a big thumbs up !! ))
