I really enjoyed the main leads story and also the supporting cast were very well rounded and had interesting stories of their own. Very funny with some actual scary moments with the stalking story line. I was really impressed by Yoo In Na's ability to do the "bad acting" portions of the character so well - they were very funny and more difficult to pull off then you might think. Lee Dong Wook was enjoyable to watch as always. All the secondary characters were great as well - funny and sweet and with their own interesting romances and storylines as well.
