My Saviour (Louis Tomlinson)

Casey is bullied and harmed. She has only one friend, Joanne, who happens to have a great social life. They both could pass off as sisters, they look alike and they act alike.
Casey's life is horrible, the only thing that keeps her going is the love for this famous band called One Direction. They are the reason she is alive.
She finally meets these five boys but what happens after she falls in love with one of them? Does everything go as expected?
Casey is now seen in a different light, but no one is sure whether it's good or bad. Casey hated her life. How much will it change after meeting the lads? How much will it change after she falls in love?
And how will it change?
