If you take Mina to the gym there's definitively chemistry between her and Veronica. And once Felicia knows she isn't the innocent little girl anymore I doubt she'd have a problem to be with Mina in a threesome. So there's plenty prospects.
Eh...Felicia might actually not want to do that with her in case it fucked up their friendship, same with Mina as weirdly neither of them seem to have very many "real" friends.
...Or, you know, maybe she'd just dive right in there because : Mina
The bi-curious stat definitely means interest in girls. My guess is that it'd determine whether the threesome that she wanted is MMF (with Ian?)
No. Unless she plans to cuck the absolute shit out of him (as in not even touch him) while she's all over the MC, followed by a real breakup, and dumping him outside naked. Then maybe. But otherwise, no. (can you tell I don't like Ian?)
or MFF (with Hana or Veronica or Felicia?).
Yes please! Especially Hana
(FUCKING YES PLEASE!!) and Felicia (assuming they're down with it in their friendship or it moves beyond that).
One of the great things about a game with fantastic writing is if the devs are interested they could create pretty much any path or outcome they choose and we don't really have to worry too much about if it'll make sense.
"And with that the MC walked off into the sunset with his lover, Frank and their 3 year old pet possum." isn't likely to happen for example.
...I'd say my preferred "ending" of "MC-Hana-Mina Happily Ever After" (if there will be such a thing) is pretty obvious.
