The Story has been Unwritten [Niall Fanfiction]

After a horrible and long period of time, Katriona decided to take control of her own life. She lived in Derby for quite a while now and after having spent her holidays in London, she 'spontaneously' decided to moved there. It only took her one day to find two absolute kind and funny people. Niall, a world famous band member from One Direction and Ruby, a very close kindergarden friend of Niall's.
Actually Kat's past shaped her in such a way that it mostly prevented to make new friends. It was hard to believe that people could be nice to her. But Ruby and Niall were different. Both of them gave her a special feeling of a comfortable ambiance.
But there was the thing with Niall. She had actually met him before but he seemed to didn't remember.
So there she was, being all happy except for the fact that Niall hadn't recognised her.
And then there was Ruby, a totally talkative, funny and smart girl who also was at Kat's age.
There was that feeling whenever she was around Ruby and Niall, that made her feel loved.

But was is really the right decision to quit her old life in Derby and to move away from her family who she loved with all her heart? Would her life had been better in Derby than in London? Would she have to repent it to have moved to London?
