To be frank, not really. There are relationships with the characters you have met - but the situation as it stands is that this family met as adults, with no prior connection and the common family denominator (dad) is now dead. So at best, they are ex-stepanythings. Which isn't really a thing. Right?
Because of Patreon's rules on incest including step siblings, we may even lean further away with a quick edit that removes the 'step relationship' on a technicality standpoint. Basically change that Miri was days away from marrying the Duke, so the relationship still stands, but the title doesn't. He only protects his new family in his will, which is why they remain in the manor. I hate bureaucracy - but gotta fund this badboy somehow so we can get the game out.
(If anyone has any extra feedback on the step-situation removal as a technicality as above, please let me know - I'd love to hear your thoughts. We weren't planning on creating an incest game, as previously stated, they are all consenting adults who have never met before.)
