AMAZING cast/characters!!!!! Lee Jongsuk is extremely talented and I've loved every single moment I've seen with him. Also, Bora from Sistar is a supporting character and she was superb. The general idea for the story was great, but when it came to the detail and drawn out storyline, I was very unimpressed. I saw it about a year ago and I barely remember anything that was actually relevant to the story. The ending was horrible and disappointing. I would recommend watching for those who like the actors, because they do a great job! The idea was pretty good, but the main male and female didn't have as much chemistry as you'd think and LJS had much better chemistry with the supporting roles (to the point that I hoped he would end up with one of them).
