I'm writing a one direction fan fiction I need a bit of help?

Defiantly Niall

I think she should betray them in a desperate act of evil in frustration that she couldn't obtain their large fortune and she then stabs them all in the night yet leaves niall as he was told in advance by the girls ex who wants to get revenge on her and niall survives and gets her arrested. He then feels guilty and visits her in prison in which they both develop a strong passion for each other and Niall bails her out. She is then discriminated against by the public because of her acts but her and Niall go of to form a group and release a meaninful heartfelt story that inspires millions and she then becomes entitled to his fortune after their marriage yet doesn't accept it as it has now become meaningless. she then lives out her life with him but cant take the guilt so she takes her own life. the end. Now you'll be the next will shakespear ;)

It mainly depends on who YOU like better.

But if I get to choose, I guess Niall because Louis is already taken in real life and I think he and Eleanor is cute ;-).
There can be more room for imagination with Niall.

It is the only factor because there's same level of everything with the two guys(hotness, sweetness, personality)

Lious!
