Don't deny both of your characterizations of the current state, I'm saying whether people like it or not it's definitely be hinted at. This clearly isn't a "harem-collect-them-all-mc-bangs-every-girl-in-universe with horsedick and they never look at another guy" kind of stories, at least not on all paths.
As to Maviarab's description, while I think anything with Kari will certainly occur much later, I do read it as the dev leaving this door open. Now whether you as a player would indulge in those kinds of paths would be up to you.
