Save Me From The Monsters

Niall has always been special. They called him different, strange, diseased. But he had visited many doctors, and none of them diagnosed him with anything. Niall was just scared, all the time. Paranoid, some people may call it. He swore there were monsters out to get him, and constantly lived his life in fear, never having the guts to tell anyone what was really happening to him.
Until he meets Zayn.
Zayn Malik has many frightening features himself. But will he be able to get Niall to loosen up, and for once in his life actually face the monsters who have made his life hell?
