I just saw her in "My Love Eun Dong". Wow, what a beautiful, warm, compassionate actress. She was so easy to relate to and cheer for in that role. I've added "Secret Garden" to my watch list just to see her in another series. iaznaB below says her character in that series is annoying, well, if so I guess that just shows that she is a good actress, right?
Yes. Absolutely. Helps a bit if you just fast forward through some of the many long musical interludes (even though the cinematography is excellent, I just didn't have the patience...) As many have pointed out, the first 10 or so episodes were very good, then they got mired down a bit. Left a few loose ends and the Finale seemed a bit hasty to me, but still provided a satisfying conclusion. You should watch it - at least the first 3 episodes, if that doesn't hook you, nothing will.
