I watched this because Kim Joon is in it, but I ended with enjoying all of the actors!!! The story is great although I did guess "who done it" from pretty much the beginning. I think that is because I read a lot of mystery books. Anyway the plot is well organized and makes perfect since. They keep the love low key which is good for me, because I was watching this as an escape from my usual romantic comedy. I also like that this wasn't a teenybopper type KD. The actors are more my age and older and that appeals to me. The theme song is awesome. I listen to it all the time. Overall I think this is a well written and well acted drama. I would totally watch a season 2. I don't give it much of a rewatch value, because I don't like watching mysteries that I have already seen. As a side note...Lee Jong Hyuk has some great lips!!! ;-)
