If anyone has any recommendations like Cruel City, that would be much appreciated. 

There is nothing like it and that's the big issue. Glad its like that but annoyed as its one of my favs (huge jubg jyubg ho fan here!).

When it finished I watched bad guys for the action scenes which was also very good but no romance.
"Bad Guys" is somewhat similar, and the movie "The Man From Nowhere" (though that is a bit gory if I recall correctly)
Though not exactly like Cruel City, My Beautiful Bride comes the closest and it is by the same writer. Deals with the criminal underworld too.
