This is a fairly talky drama (although there's action and violence too), but I found it very engaging. There is a ton of plotting and scheming going on (besides the CCP spy the mole hunt is looking for, we learn fairly early on that there's also a KMT spy in the mix - not to mention everyone's own agendas). It's full of unreliable narrators (don't necessarily trust the flashbacks that are shown). I enjoyed watching everyone's interactions as the cat-and-mouse game unfolds and I particularly adore Gu Xiaomeng and Li Ningyu's chemistry! I also felt like it has a pretty satisfying ending.

As may be expected from the genre and time period it's set in, it does have a fairly high body count among the main cast and I think most of the content notes you'd expect for a WWII era spy drama apply, especially in the second half of the drama.

I really enjoyed this and I'm so glad it got fansubbed!
