You can.
When you are presented with the option, just refuse it.
played the game, and hated it, it full of NTR and sharing content. trying to avoid it all is a constant and anoiyng work, not ewen shure u CAN AVOID it all. needs a walkthg so u know what choices to make to avoid all that NTR/sharing content that seems to take up most of the game. feelt like a cock game to me
