The dev has said there will be no incest, so that would rule out throuples with the three main LIs. And the dynamic of the three of them do not lend well to sharing. They've also said it won't be a harem, as again it doesn't fit the dynamics of the family.Suzi though is perfect as an LI but i wonder how she gonna fit into the relationship dynamics. I believe Charlotte is the default unavoidable LI. So we getting throuples?
You saw what Suzi did when he moved into her room at the house, can you imagine what she'd do to the MC if he stepped out on her?
And Charlotte's personality and past traumas would not lend well to sharing, either when trust is such a big thing of hers.
