Atrabilious (2013)

It's been a year and a half since Guy's best friend stole his girlfriend. He's wasted that time on worthless activities like watching wrestling with his friend, rekindling a romance with a racist, and maintaining an apartment that is a constant reminder of his failures. When a cute neighbor moves in upstairs and a small crush turns into a chase, Guy finds himself falling in love with someone who might actually be worthwhile.
