"I'm Harry by the way." "Ni-Niall." he answers. "Thanks for this man. I owe you big time." And that's how it all starts. That's how Niall becomes Harry's "Boyfriend" fake boyfriend that is. And yeah Niall had a huge crush on Harry before this. And he was dying for a chance to get noticed by him. And he should be happy, except this isn't really what he had in mind.
