well, the text has not been edited yet so I might tweak the story a bit before I let it voice over.
there's no ntr route, when a choice is highlighted red it means that this choice will end a relationship with the person. Those are choices I put for each character very early in their story, so if you are not interested in that character you can end it right away. And if you decide to end a relationship you won't see any more story parts of that character again, so no, I won't proceed with an ntr route.
