Not looking for action or spy drama.  Looking for romantic drama where both ml and fl respond to the agressive/bullying behavior with equal agression.  A simple slap after unwanted kiss etc is not enough.  How about a black eye or a broken nose.  That will make him think twice before he does it again.  I'm sick of these overbearing ML and meak FL.  

The Killer Is Also Romantic  is the first show that came to mind when you mentioned Mr and Mrs Smith. Neither is the ML overbearing nor is the FL meak (although she pretends to be innocent at times). It's a fun drama.

I didn't get the beat the s*it out of each other vibe from it.
