Hi! :) I'm Mei, and I play Alex here. He's a rising senior and the president of the Sigma fraternity. He lives to party and have fun and has very little ambition. Because he comes from an incredibly wealthy and well-known family, he's never had to worry about money, and thus doesn't really take school seriously.
He'd probably know Olivia, since they're both from the frat/sorority scene and are both seniors. I'd say he's flirted with her relentlessly up until now, because that's just the way he is. He doesn't really take no for an answer.
