After watching so many Korean dramas, I might say that this is so worthy to watch. The characters are so good in portraying their roles, the emotion that they show was all conveyed well. Great story line. My fave characters were Song Yi Soo and Song Yi Kyung. I mean Scheduler is my main reason why i watched this. But after a single episode of this, i got hooked. i cried, laugh, think of what will happens on the episode, and sometimes my heart can't fathom a single word after watching it. And now i'm rewatching it all over again as if this is my first time to see this,..it has the same effect..my heart beats faster than the usual.. hope that everybody will feel the same
