The Other Horan (Zayn Malik/Niall Horan/Andy Samuels)

Bernadette Horan, last name sound familiar? Yeah, she's Niall Horan's twin sister. She lands herself in hospital and Niall makes her move in with him. The problem is, he didn't know how easy it was for Zayn to get to her. Isabella Nolan, Niall's girlfriend, but he thinks fame's getting to her head, so now, you could say they're ex's. Claudia Cirillo, she doesn't really have the best life, and even though Andy Samuels makes her happy, it lasts about two days before he stuffs up. These girls have problems, big ones. Throwing One Direction and a few friends into the mix definitely doesn't help. Those three relationships aren't healthy, but they aren't toxic. They'll kill each other whether they're together or not. Although, maybe it can all change, maybe they can move on from their arguments or maybe that's a load of crap. You're going to have to read on to find the truth.
