The Jerk Theory

Niall was an ass and got the girl.
Liam was the good one and got screwed over.
He always got screwed over.
Well, if Niall could be an ass and live happily ever after, then so can Liam.
"You either learn how to play the game, or continue to get fucked over." Harry told Liam.
Good advice?
We'll just see how Holly Jackson feels about that.
