This is the first K-Drama I ever watched, I never expected to like it as much as I did. It's so different from a lot of stuff i've seen in the U.S. I was so happy to find a K-Drama section on Hulu (sorry if you don't live in the U.S. or Japan, Hulu really is awesome). The acting and storyline in this is awesome! Again, as some other people have pointed out, it can be a little far fetched at times but hey that's the point of watching a show right? If you're on a break from school or something or have a good amount of free time, definitely go for it. I'd also say it's a good stepping-off point drama for friends that you're trying to get into it (along with Boys over Flowers...either one)
