I must say, watching this show, I actually felt like a spectator, rather than really being invested in/caring about the people.
There was a lot of "going through the motions" with the cast, sometimes due to the writing, sometimes due to lack of expression of the actors. Instead of a typical love triangle, this one had something like a love pentagon. Everyone was in love with someone else!

Since this show is 10 years old, the video quality and the sound quality were not up to par. During the music scenes, the sound would vacillate between being clear and then going into what sounded like a tunnel. The songs, however, were good. I liked how they were able to combine traditional music with contemporary music. Then there were the clothes and the hairstyles - I kept wanting to give Park Shin Hye a brush!

The main couple's storyline was cute, though I couldn't actually feel when or why they started to like one another. His change was especially abrupt. Their scenes together were cute. There were a couple of open-eyed/static/fish lips kisses which really irritated me. Consequently, it was difficult to buy into the chemistry between the two.

There was the obligatory time jump, which found her having a meteoric rise to fame, and the rest of the cast pretty much staying the same. The break up before the time jump was lame and they finally got back together in literally the last five minutes of the show. Needless to say, I felt like I had invested so much time that I wanted more.

So, overall, it had some cute moments, but I definitely don't feel that I would need to watch it again.
