...who was also his long-time babysitter, making it even more "might as well be family," again, especially if you want to see that anyway. And you even have an option to bend the dialogue that way if you like, at least with the scene at her office.
Three threesomes have been strongly hinted in the last update--MC with Annie/Luna, Alex/Dalia, and Nova/Penny. Given that MC's only had sex with half of them, my suspicion is that it'll be a while before we see them, but the hints aren't very subtle. I've also seen it claimed that the game dev has confirmed every girl gets at least one threesome; I think it was on his Discord where he was said to have said that. Nancy's all but suggested MC get with at least one of her daughters, but no indication that she'd join in--and given Patreon rules, probably not, so her threesome would then be with someone else--I might guess Annie, just because Nancy can't get over how cute Annie is (and I agree with her there). But I guess this discussion belongs more in the Eternum thread...
But I guess I can argue this is partially on-topic here--Riley did recommend Eternum, after all...
