Well, It was originally an incest game like NLT Media's previous works. It just happened that, Patreon prohibited incest themes on their content so the Devs made a small iteration to the story and character's relationships. NLT Media was well-known for incest only contents.NLT is not responsible for taboo mod, these are incest patches which are fanmade and have no link to the developer, so direct your question to the person who makes these patches and ask him to include the dialogue, since this is NOT an incest game
