yes we do.No we don't.
At the start of the game the MC is love with Josy. Later on he falls in love with Maya, it's why Josy and Maya not telling the MC about being together even though neither has any idea that the MC knows who the other is, hurts him so much, because he's in love with both of them.
And then, he falls in love with Jill, tells her he's in love with her, all before the player is given any input.
And yes, Zoey should be handled easily enough, but it won't be. I guarantee you when Zoey comes back, MC will have have another emotional freakout and run away.
I have four saves where MC is in love with only one girl (Sage, Josy, Jill and Bella) and I am who decides if during the ep7 party MC stays friend with Sage or takes their relationship to the next level. You need just to be coherent with your previous choices.
