Advanced music

Louis Tomlinson, Cher Lloyd and Niall Horan are the 3 most popular people in school. Liam Payne, Zayn Malik and Harry Styles are the outcasts.
Liam is gay but he would never tell anyone, especially since the person he likes is his arch nemesis, Niall Horan, whos livin' it up in the rich part of town.
Louis is bi and is in love with Harry Styles. But louis knows that it would never work out because of the social status.
Zayn is the straight one of the outcasts and is in love, with Tomlinsons step-sister Cher, who has never ever in her life spoken one word directly to Zayn himself.
So what happens when all 6 of them get put into an advanced music class together, and are forced to spened there free time together working on project?
