Up to this point, Louis and Harry's relationship has been perfect since all the lies and cheating stopped. That is until Harry leaves for Uni, even Niall and Zayn, who are attending the same University, notice he is changing. He's out late, skipping classes and hanging out with the wrong people. But what's worse is he's began ignoring Louis, unreturned phone calls along with messages he never seems to get. Liam and the boys try their best to help Louis stay strong, but when he decides to take matters into his own hands to find out what's really going on, he heads for Uni and what he finds isn't at all what he expected.
