The title sums it up.

It wasn't a coincidence that he recognized her. She wasn't just anyone. It was Rey. His Rey. The girl that he knew since childhood. The girl he loved. The girl whom he thought was dead. The feeling in the pit of his stomach had returned, after all these years. Damn it, he still loved her. But he couldn't. Ben had loved Rey, but Kylo Ren didn't. Ben was dead now, and always would be. ** AWESOME COVER BY JEABOOKS
