Out of all the Korean Dramas I have watched, this one takes second place. There is not telling how many times I cried watching this. The plot is so thoroughly thought out and unravels as smoothly as possible. The actors are so great. It has comedy, romance, and mystery. Everything you could ever want in a show. This is a must watch for everyone. It really teaches you about life. I highly recommend this. But it is so funny that Yook Sungjae stars in this drama and Guardian: The Lonely and Great God. A classic and a classic in the making. I am seeing a trend here.
