Jet Black Heart (Ziall Horlik) AU

Everybody's got their demons, even wide awake or dreaming.

Niall Horan had his secrets and his demons that he covered with a smile. He never let it show, even to his best friends. They never caught on either. Well, until Niall fell for one and it all slowly came out.

Zayn Malik was Niall's best friend since birth. They've been through everything together. They were partners in crime. They were opposite in every way possible, but that's all that drew Zayn to become infatuated with the Irish boy.

Are Niall's secrets too deep to ever be fully uncovered? Will Zayn still feel the same about Niall if he can uncover the demons from a jet black heart?
