The story : Two people who hate each other are forced to get married. And to work together to solves cases.
As they do, they are gradually drawn to one another. Will love or hate win?

Pros:
- Strong clever detective Female Lead.
- Strong clever military Male Lead.
- It is the fist time I have seen a heroine, daughter of a concubine, who is loved by her entire family and not bullied. Not a cliché. Yes (*_*)
- Chemistry is fire and the settings make it even more beautiful to watch.
- Characterisation is outstanding for Male Lead (Ding Yu Xi) who looks very manly as the great Shen Du.
- The inquiry is very good. Complex and involving many people. I try to guess the outcome as it progresses but I have a hard time doing so.
- Comedy is just great between the leads. I hope they had more comedic scenes.
- Cinematography is great.
- Action scenes are worth watching. There are few but when performed, OMG they blew my mind. Especially with Male Lead. I am still in shock (*_*)
- Overall the story is good and entertaining.


Cons:
- The mystery unfolds piece by piece and it can disturb some viewers. But like in Agatha Christies novels, you end-up getting the answer.
- Misunderstandings (who is Male Lead, who is Female Lead, what they do on their own...).
Sometimes they don't communicate enough.
- I don't like childish Female voice dubbing. Guess what ? The Female Lead's best friend has one *sight*
- Female Lead is not perfect, her many flaws could spoil your fun.
- Lots of unrequited lovers from the second arc for almost every cast member. This should be titled "conspiracy in love island" o_O

Overall :
This is a good drama. So I recommend it if you like case solving duo with strong Leads. You might like it.

And the OST is great.
