Even though this isn't my usual drama's genre, I hereby said that this drama is one of the kind.
Really enjoy the story and the drama production. Big shout to not only the cast but also all the team behind this drama. It is well thought and well made. Every cast can portray the character well, every scene was very vivid (exclude that bomb scene which killed Dr Xu), even the music (especially Guang Mang) really gave me some goosebumps.

my only complaint is the ending which seemed to be a bit rush, which gave that all anticlimax in an episode. I feel they just want to "Wrap it fast" and kill every villain in a blow, which is less than 20 mins. Kind of disappointed but also glad at the same time.

Just watch the drama and don't give up halfway. I know the FL seemed to be a jerk first, but in the end, she redeemed herself.

Additional notes:
I wasn't steven's fan before, but I have to say he really did a great job in this drama, really love the character of CYZ. Elvira did a great job too to portray the female lead who had a very difficult personality and character, to begin with.
