Looking for an alternative name for a Korean action movie, or the name of the director, or actors starring in the movie. The English title was "True Man", but I can't seem to find it when using Google. The movie follows a man, who along the way meets up with a waitress. They go on a road trip of sorts and get embroiled in some gang-related affairs. Some other characters in the movie are a group of three guys calling themselves something like "The Red, Yellow, Blue Gang" and each member is fully dressed in one of these colours (even their hair is dyed the same colour as their outfit). The main character has some dialogue he says a few times throughout the movie referring to the notion of what is a "true man". Can anybody help?

A Man Among Men

You are a legend. Thank you so much.
