That's actually something I've been a little concerned about, as far as my own likes and sensibilities go. Specifically about Jamie and Shauna. I think I'm still in Day 8 btw. When Tali asked about whether or not Jamie and Shauna ever kiss, the MC said something along the lines of (unless I really misunderstood) "As long as it's just friendly kisses I don't mind."
My first reaction was "EXCUSE ME?!!". Not only am I rooting for them to become sexual together, but I couldn't help but think, "Man, what a selfish ass!". I mean he at least acknowledged that he was a hypocrite for not wanting to see his chicks be with other dudes, but they all felt the same so that was all gravy. That was like winning the lottery of a one-sided poly relationship(s) lol, but everyone felt the same about it so
But Jaime and Shauna are a whole other matter. I want to see that shit be a real triangle. To be in a throuple but insisting that it be and stay all about you. Ugh. I don't know. Maybe I'm just misinterpreting things. Also I literally just woke up so I'm a bit groggy
I feel like there's been some build-up and teasing for them possibly becoming attracted to each other and acting on it though. In a good way, not in a hiding it from the MC way or anything. I'm personally going to be super-disappointed if it never progresses into anything. But, as always, to each their own.
