Thriller Drama with cool male lead

Just want a thriller drama where the male lead is op. Like he is good at fighting, shooting and everything. Want one with romance. I want it to be modern as in the setting can't be in the past got to be in the present. Would be cool if mc is in a task force but not needed. Really liked city hunter male mc and how he isn't a police officer but is still op. 

didn't like the female from healer would like the female lead to also be op such as good fighter and smart

When A`Snail Falls in Love - Chinese. Brilliant. Love is a slow burn. Action is epic. 2 excellent female roles. 

Liar Game - Male lead is brilliant in pyschology(also: human lie detector)

Squad 38 - Seo Inguk as a really really good con artist. Show has little romance.

I Remember You/Hello Monster - Seo inguk(again lol) plays a genius profiler + park bogum. This one has more romance compared to other thrillers but doesnt focus on it.

Girl Who Sees Smells - This one is more of a romcom but also a crime show. Male lead lost some of his senses. Hence he's good at fighting.
