Obviously most people don't play porn games to be the dude who never gets laid and watches the relevant female get railed. I personally don't think the Delusria is intentionally trying to make the game NTR, just trying to eat your cake and have it too. Because I imagine most people who see the cute girl also want to have sex with her.
This game would honestly benefit from some sorta slut meter or metric. Just have that value be what procs variations on h-scene and encounter dialogue (saves need for making variations on artwork). Maybe throw in some anti H items to protect the Salvor. That way both sides get what they want.
Don't want her to get violated? Great, invest in that. And she'll reciprocate by being more romantic and fixated on you. Whereas elsewise she'll be slutty.
NTR cucks get what they want. NTR crybabies get what they want. All while keeping it in the gameplay as opposed to a "if I didn't see it, it didn't happen" toggle.
