PACING: This drama has natural pacing, there are slowish moments and it would have been perfect as a 40 ep drama, but this is one of the most addictive and well-written dramas I've ever watched. When you watch this drama you can tell how much the scriptwriters care about building this world. There are little details like the neighbours or family moments that WOWED me!
- I love it when dramas don't have to establish all these extra characters, but put so much thought into them anyways, it makes this drama come alive, and the world feels realistic, most of these people also get referenced throughout the drama

CAST/CHARACTERS: The cast is phenomenal. The acting is so convincing! (Especially the main 3 leads, plus the entire 2nd police squad)
-The characters are complexed and not one-dimensional, there's so much character development.
- GU YAO DONG IS ONE OF THE NICEST CHARACTERS WRITTEN. His character stays consistent the entire drama, he will always pick to do what's morally right even against all odds which is so hard to do in the chaotic era that this drama is set in, so the ML is so likable and it's hard to play these kinds of characters without annoying, props to Li Yi Feng!
-the female lead is loyal, smart, badass. The romance is slow, but for me, it's a good thing since it allows the relationship to progress naturally
- Ji Cheng is probably my favorite character, he's so charismatic and I love every scene he's in!

THINGS I LOVED:
- The heartwarming family moments, and bromance between the chief (Ji Cheng) and Yao Dong, basically all the relationships in this drama are so well written and tugs on your heartstrings!
- THE DIALOGUES are SO INTERESTING! (Similar to Nirvana in Fire, this drama is more character-driven and the most intense scenes for me wasn't the action or spy scenes, but actually the schemes and mind games between the officers and the main characters
-THE GU FAMILY ARE SO PRECIOUS

MUSIC: I made fun of the op song so much the first time I heard it but after 20 eps it started to feel nostalgic and suits the drama, I actually started humming it myself xD and by ep 51 it's like the national anthem where I can't skip anymore haha xD

Hopefully there will be proper eng subs for such a great drama! When there is make sure to give this drama a chance and have patience since this drama might not have the fastest pacing, but I swear the payoff if worth it! IT IS A BEAUTIFUL, HIDDEN GEM.
