Agreed with 4Zero9Zero. If you want to see "all" the throuple content, you'll need two saves. One that favors Josy and the other that favors Maya. Anytime you must do single events, choose the one that's favored for that save.
It'll affects a number of conversations in several chapters including Episode 11, as well as single moments/scenes.
So far there's only one scene I've found that favors balancing both. That's when they compare the MC's bodycount with them after the Halloween party. There is a change in the conversation and RP points if it's perfectly equal (yes it is doable!), or more/less lopsided to one or the other.
