Sort of makes sense, but at the same time it doesn't, at least not right now. Josy has already expressed her unhappiness in her relationship and such, which apparently is with Maya, and well, she also approves of cheating if it makes one happy, not really the kind of person I want to be with, cheating is never a-ok, it makes you a very shitty person. If you're unhappy, then break up, it's as simple as that.
As for threeway relationship, I'm not at all for it, I never go for that in any game, much prefer monogamous relationships, because I simply don't share my girl, not even with another girl
