"You can call me, when you're lonely, when you can't sleep, I'll be your temporary fix."
Diana Holmes was Niall Horan's best friend. No questions asked. Well, other than the boys of his band, One Direction. She was there when he needed her, via. Skype, message, or calling. They started a collab channel on YouTube with him before he left for XFactor. She would get asked at school to bring girls, and some boys, autographs of the famous Irishman. She would tell them that she would 'see what she could do' but she real knows that she would never ask Niall to do a thing like that, with all he has to do.
When Niall decides to come back to Ireland, Dublin to be exact, Diana is ecstatic. She gets to catch up after a year of no physical interaction with Niall, other than the occasional wave in a concert. She sets everything up, the room he'll stay in in her Dublin house, stocked up on extra food, and everything goes according to plan. Niall comes, Niall stays, but the pap aren't to keen.
