Past Or Present? (A Niall Horan and Harry Styles Fan Fiction) (*ON HOLD*)

'I awoke to the annoying sound of beeping, getting louder and louder every time I refocused more. Where was I? What was I doing here?'
When Scarlet Edwards loses approximately a year of her memory due to a drunken car crash everything changes, even the way she thinks. Before the treacherous crash, she used to date Harry Styles who is one of five members of the world’s most popular boy band: One Direction. She used to love everything about Harry, from his all dimpled smile to his cute curly hair, the way he dressed and walked but now from the minute she set eyes on him she finds him irritating and impossible to get on with. Harry understands this too and begs her to stay with him and give him a chance and she agrees, but only not to hurt his feelings. Time goes on though and she realises that his type of life style is not for her. She doesn’t want to go out clubbing and partying every night, watching him flirt with stranger girls, she wants someone differential to that.
Then she meets Niall. According to Harry, she and Niall were really great friends and she decides she wants to get to know him more. She and Niall become really close and she goes to move in with him when she has had enough of Harry and obviously, she and Niall get closer than expected. She and Niall both fall in love. But what will Harry's reaction be to this? How will this affect his and Harry's friendship?
Harry doesn't just want to stand there and watch what he once thought was the love of his life snatched away from him and as he begs Scarlet and shows her his true amazing side she has to make a choice: Is it Niall or Harry? Past Or Present?
