He's not her cousin, they say that so it doesn't look weird that a random boys living with them, which would make people curious and then find out he's a prince, it's just a cover
He's not. They're not related at all. But because he was in danger he was adopted temporarily by the countryside nobel and pretends to be the cousin until he could reveal himself as part pf the royal family and fight for the throne.
not actually incest. Also im not condoning or defending incest but yall know that actual royalty and nobles and stuff have always had incest happen right? nobles don't breed outside the pool. incest is encouraged so they keep the bloodline pure.
Why tf is incest so normal in these tf
