You've only got one shot (One Direction Fanficiton)

The tricky thing about life is no matter how hard you try, you can't change some things. Life offers you a chance and if you don't use it, it's lost forever.
Valerie is a person who missed hers. Or, she let somebody else miss theirs?
This is a story about happiness and the lack of it. About that one day when you wake up and realize that your life just flew by and that you have become the person you never said you would.
This is a story about second chances, which only come to those who are worth it.

Valerie Smith Styles has a best friend, who is also her ex husband. She still loves him, but he missed his chance. Harry is sure that if he could relive that moment, he would still have her. The problem is that's impossible, isn't it?
Until one day, he wakes up ...a bit younger.
