Broken Heart (A One Direction Fan Fic)

Lisa, a 17 year old girl, is famous boyband One Direction's Zayn Malik's girlfriend. She has everything in the world she could ask for. But it seems that things in love are never that simple. Her sister, 15 year old Lily is up to steal her love, her life.
On the other hand, Zayn has his own problems. He never wants to lose Lisa. But Lily is forever stalking him. She is crazy about him. Zayn can't tell this to Lisa, because Lily is her sister. She would just think he was making Lily bad in her eyes. On top of that, the media and his fans continue driving him crazy. 24X7.
Lily just doesn't understand why Zayn won't love her instead of that asshole of a sister. In depression, she cuts herself, pleads to Zayn. Zayn gets into a relation with her just to keep her from cutting.
A complicated love triangle, when all of a sudden, one goes out. The triangle is broken. And so are hearts, never to be healed.
