the sibling here is not blood related at all so there's no incest thingy here and this story that first was a novel and now adapted to a manga
what? aren't they? Sigurd and Juliette are both born from the same mother, just have different fathers, that's what it says in the manga at least
WAIT NOW I REMEMBER, sorry, Juliette is Andrim's second wife's daughter right? sorry lol
