When an extremely attractive but overly nice bar tender cannot find love, he then recruits his buddies to transform him into be a jerk, until he lands the girl of his dreams and loses her because of his new attitude

How's this "When an extremely attractive bar tender cannot find love, he then recruits his buddies to teach him how to be a jerk, until he lands the girl of his dreams.

You could tighten it up a little bit as its a bit long, I agree withe the above comment, scrap the ending

You should leave it ending with "...until he lands the girl of his dreams" It kinda leaves a clift hanger. Creates curiosity for whoever is reading it. Adding the last part kinda spoils everything.
