I watched this drama mainly to see Joo Sang Wook after coming off watching Cunning Single Lady. This is an older drama and his acting isn't nearly as good as CSL, although it could be partly due to the character he is portraying. He almost looked like a different actor and was more wooden in his delivery. This was the first drama I've seen Park Shin Hye in and she was very cute. This is a family drama, so there are a LOT of episodes. While it does get laggy in places due to length, I did watch every episode and enjoyed all the side characters stories as well as the main storyline. The actors did a good job for the most part and I think that is what made this drama watchable. The big secret is what drives the plot along, but there are some secondary plots and romance that help round it all out. I probably would not watch again, but mainly for the length and age of the drama.
