Story: It´s a Sequel of the first season, so you Need to watch the first season. It has pretty much the same plot, if you can consider it plot. I think it´s just how they investigate in different cases. A bit like Vampire Prosecutor (that aired at the same time, both seasons and on the same channel OCN). Just cases they work on and a bit of a plot in the Background. Sure, it´s nice to see all These different cases but I would have liked it if they Show more of the Background Story. Acting: It was very good and I espescially liked Choi Woo Shik as Park Min Ho! Music: It has only 2 Songs or so, and yea.. :D But nice Songs! ^-^ Overall it´s a very nice Drama, that got me hooked until the last second, although it has got it´s flaws in the storyline. But.. this ending! Can I have a Season 3?? :D
