With a few exceptions all the older dramas I've watched sucked. This one is pretty good for its age. Park Shinhye + Jung Yonghwa combo worked out quite great, which came as a surprise, since I did not like Yonghwa before, but as it turns out he is a much more talented singer than I thought & his acting was okay too.
The story with the big play & the villains doing things to make things harder just isn't good, the writers did not try real hard to make it interesting and relatable, luckily in this genre this isn't a major issue. There is a love square, but it's very weak, the second leads don't cause many issues, this is very applaudable for a 2011 drama really. The secondary characters could have been more interesting, but there were a few rather funny ones, so it's okay.
I liked the music, my only gripe is that it was quite repetitive at times.

I wanted to watch a lighthearted romcom, this mostly delivered, if not for the 40 minutes of forced separation makjang in the last episode, I would have probably rated it a 9.
