Do I know you? Those were the only words Riley Douglass ever heard Louis Tomlinson say to her. It got to the point where she flipped out on him at his "Farwell Party" right before he left for the X Factor. With that being her last memory of Louis Tomlinson, she tries to push him from her mind, and forget about all those years she's tried to get his attention. Deep down she had a crush on him, but the longer she ignores him, the more her feelings stop for Louis. But when Riley gets dragged along to a One Direction concert-well, let's just say, things get crazy. Who would have thought four simple words could do so much? Do I know you?
