action + romance kdramas?

I’m looking for something along the lines of K2, Healer, Vincenzo, Descendants of the sun and Undercover High School, with a ML that’s either special operations, or has an action packed job like healer! I’d love for the ML to be really good at fighting but also romance 

• My Secret, Terrius - Great action, only suggested romance though. Highly recommend!
• Flex x Cop - Action and suggested romance. Haven't watched it but it fits your description.
• Taxi Driver - Again, lots of action but not much romance, but the chemistry is there.
• Vincenzo - Action and romance. Probably fits your description the best.

1. Man to Man
2. Faith
3. King2Hearts (though the FL is a better fighter the ML is pretty good too)
4. Military Prosecutor Doberman (FL is the better fighter but ML is good too)
