Ren knew the guy very well. He was one of Evie's many admirers but ended up as Rayna's boyfriend. He was their senior but still looked youthful enough to pass as their age group.
Money could make that happen, apparently. It was the Elixir of youth.
Looking at Dimitri before he shifted his attention to Rayna, Ren even had a hunched that the two were dating long before Rayna even asked him out to lunch and movies as payment for sharing his homework with her. Just from the subtle exchange of gazes and he knew that the two already knew each other.
But right now, he didn't care if she and Dimitri ended up together. He'd only make sure that Rayna would pay from how she toyed with him in the past.
Ren smirked and looked away. He already knew what Dmitri was going to say, so he didn't bother to spare the guy another second of his attention.
