This was a really great drama! The characters are interesting and they develop pretty well. One thing with this drama is that it slows down a little in the middle( episode 4-6) but if you hang in there and watch it through, it gets really good.
I will say one thing though, I wasn't that impressed with the ending, it kind of made me feel like there should have something more or that they were trying to rush it.
In the end, it is still one of my favorite dramas. I still have most of the songs stuck in my head.
