I think I'll be adding or tweaking his bio a bit, but here's what I have for Niall:
Niall Horan (19/20) - Niall took a year off from his studies to work on his music career (with the band) and if he's being honest, he's just really lazy and couldn't be bothered after high school to pursue a higher education. Music is all he has and he's pretty confident he's going to make it successfully enough, much to his parents' dismay. He camps out with whoever will give him a bed for the night (mostly Louis) since he can't really hold a job for more than a month due to his overly relaxed (again, bordering on lazy) nature.
Despite his aversion to hard work that doesn't have to do or further him in music, he's an all around likeable guy and easy going. He's friends with everyone.
I feel insane and I will work out the kinks/relationship with Louis an Niall soon. I hope everyone likes this!
Edit: Niall isn't a total mooch, he'll bring the beer to the party with whatever money he has saved from his short job stints, and when he does party, he's a total animal. Despite being Irish, he can't hold his liquor all that well.
