You know, I was thinking, I think this would be kind of interesting. Now that We know, that even if you are Together with both of them, there is a Josy or Maya specific path. combine this with the comments Maya made in ep5 about, what if She realize she doesn't like boys. I was wondering, maybe if you only Focus on Josy, and don't do any sexual thing with Maya, She won't come around. She won't be "Converted" She might like the MC as person, emotionaly, but she wont be in to him sexualy.
I think that would be Interesting, this could lead to a Josy solo path, or her choosing Maya over MC in certain cases. and Vice Versa. if you focus on Maya and less focus on Josy, the outcome can be the same. and in order for the Threeway Happy ending if you want that, You have to Balance Josy and Maya as much as possible.
I like this idea, and I think it's logical. You need to work for the certain ending with them
