I'm with you man. I can go either way with incest too. It's not really one of my kinks (though siscest is bestcest

).
I usually like to go with whatever it seems the intended relationship is. Usually when there is a choice like "what is she to you?", that's usually a pretty big hint that incest is canon, so I initially went with "sister". However a lot of the dialogue feels more like childhood friend makes more sense. Like, Clarissa doesn't live in the same household, or how it's "Clarissa's mom" even if you chose the "sister" or "cousin" variable. Another moment that comes to mind was the "Corey vs. Steve" convo in the girls locker room. If they were siblings or cousins, then it seems like the other girls would have teased Clarissa when she made that comment about him. Like "
Oooooh Clarissa wants to fuck her inverse_clarissa_relationships
!!!, but they didn't do that. They just simply told her to pick from two other guys.
...but then she mentions bathing together as kids which is usually an incest trope, and that dialogue is the same whether she's a sister or childhood friend. So its like 90% feels like childhood friend, but 10% feels like they might be related? A childhood friend with a really
really close relationship growing up?
It's hard to explain, but usually when incest is intended it's usually more obvious in the dialogue and that it was changed for patreon... but it feels like the opposite in this case. It's like she was legit written to be a
childhood friend, but the dev added the incest option afterwards for the sake of fan service for incest fans. Pure conjecture but that's the way it seems to me.
Eh, anyway I think I'm vibing more with her being a childhood friend, so I'll probably just redo my saves lol.
