Thank you, Nathan (A Nathan Sykes fan fic)

Riley Carter was once suicidal. No one knows about that, but a small few. She tried to kill herself once, but was stopped by a stranger named Nathan, who’s name she didn’t hear and face she didn’t see again for two months, until it was plastered everywhere. “Nathan Sykes of the Wanted.”
Now, two years later, he returns, and searches for the girl who’s life he’d saved, hoping to find her still alive.
When he doesn’t recognize her, she decides to leave it that way, but he can’t seem to shake the feeling that he knows her. Will she come clean and finally say Thank you to Nathan?
