Unforgiveable

Liam and Kay where best friends from the time she moved in next door. When they turned 13 they started dating. At the age of 16 they where in a bad car accident and Kay was told Liam died and Liam was told Kay died. But neither did. They where told that so they could heal and because Liam was driving and Kay's parents blamed him for their daughter almost dying. Kay's parents took her back to Alabama to keep her away from it all and when Liam became famous with One Direction they had to keep all that stuff away from her as well. When she moves to London when she turns 20 she moves in the same apartment building as Liam. Kay still has a hard time remembering things and she just now is able to get her licenses back because she had a bad head injury. Liam never stopped loving her and was heartbroken when he was told she died. But him and the others are just kicking a soccer ball around in the hallway on the floor they live on and the ball hits a girl in the back of the head. Liam about passes out when he sees who it is. What happens when he sees her? Will she remember him?
