It wasn’t Rayne’s fault, Cameron just assumed she was one of his rich friends and not one of the waitresses who served them. But he’s nice and sweet and genuinely seems like he wants to get to know her. Giving in to her desires, Rayne goes against her better judgment and continues the charade. He’s the forever kind of guy, that once in a lifetime love. Now that she’s had a taste of it, of him and his world, she doesn’t want to give it up.
That choice isn’t hers to make, though.
