May be you are mistaken the duke and the Duchess are not biologically related at all they both belong from different family but were bought up together as the Duchess Anissa was kidnapped at very young age and bought to Langrange mansion so there is nothing like they got married to continue the pure bloodline. So why are you becoming mad and disgusted????
I’m personally not mad like I said, but they were raised up like family, family doesn’t need to be blood relates to be family so seing as they still ended up together is kinda weird ( hence why I said disgusting ) but I don’t find it THAT weird cause it USED to happpen before to preserve bloodline ( how hemophilia began ) never said they got together to do that
I’m not as mad at others (still disgusted ngl) but o feel like back in the days it was really common occurrence to marry in the family to perpetuate the bloodline so I’m not THAT chocked but I feel like some of y’all got their mind clapped
Anyway baby girl if you play with your sibling like that you’re gonna kill them
