Between Us Now

They have many misunderstandings. 

The sport guy will get kinda outed for helping his classmate who gets bullied. The pretty guy doesn't know he is in love with the sport guy and thinks the shi*** feelings he has about his friend and the small dude is because his friend turned gay for some other guy and he hates gays.
They graduate high school without clearing anything up between them. Sport guy still thinks the pretty guy is homophobic (he did cut off contact and was with all those mean guys from their class) 
They still go to the same college but the pretty guy left for USA to clear his mind(?) and the sport guy went to the military when he heard the other guy left.

They end up in the same year in college and pretty guy wants to be with sport guy again & feels shi*** about his past actions towards sport guy.
That's what I got from the comments...
