Niall Broke Into My House? (A Niall Horan fan fic)

Adara Buble is the daughter of Micheal Buble and Josh Groban. I've been kept a secret for my whole life. I have gone to school acted like a normal girl, but with a different identity. Even my closest friends don't even know my real identity. One day I was home alone and someone breaks in. It was Niall Horan. But why?
