This was styled a bit differently than all the drama I've watched thus far. There was an overarching mystery to solve, but every 3-5 episodes there was a new murder/plot to contend with. It was more grim and serious. And while there was romance, it was more of a secondary thing. Honestly, I really enjoyed it. I just wish there was a season 2, to resolve the few lingering questions at the end.

Things that impressed me:
- The females (all of them really) in this weren't annoying. There was none of that overly cute and dumb thing that is rampant in C-Dramaland. The main female is an assassin and I love her iciness to bits. LOL.
- The wuxia aspect was nice. Lots of fighting. Who doesn't like that?
- Rachel Wang, Wang Yan Yang, Du Ya Fei, and Wang Xing Wei were pretty to look at.
- Even though some parts were predictable, there was still other parts that weren't.
- The fierce bond of friendship between the two male leads. Bromance. (Not the BL kind.) <3 <3

Overall, the drama was wonderfully executed. Everything tied together really well in terms of: production, script, acting, cinematography, etc. It's truly the result of great teamwork.
