Romantic Thriller with strong Fl and Ml

I'm looking for dramas where either both leads are detective or one of them is. Even if they aren't, there should be murder involved. Plus there should be some romance between them as well. Modern Chinese dramas are most preferable. Tho any other country is okay as well. 

But I want both leads to be equally intelligent. 

Shows that I loved:

Memory lost (my most favourite) 

Love Me If You Dare (tho fl isn't my fav but it was amazing due to ml) 

The Confidence (leads aren't detective but strong) 

P. S: I've tried When a snail falls in love but I couldn't get into it as fl is too slow. 

 Lou:

Kidnapping Game - romance starts pretty much from the beginning. The case is not the absolut best but the romance is truly golden here. strong fm and ml. neither is a cop but it really is a well done drama

Trinity of Shadows  - really good case plus great romance. But the romance does take some time to develop. They don't start out liking one another.strong fl and ml.she is a cop, he is a political figure.

Stealth Walker - she is undercover in a drug ring. he is one of her targets. or is he? This one has strong ml and fl. its good but it does take a while to get warmed up to the fl. has romance

Thank you so much. I'll look these up. 

He Is Psychometric is pretty similar to what you describe. The ML is definitely not as smart as the FL but makes up for it in other areas and he gets smarter as the drama progresses.
