The duke adopted her from the orphanage
I thinh the Promo is misleading.
FMC is in now way related to the Duke, he simply adopted her because the Imperial family asked him to.
And it seems there's no brother...
ohh i thought she was his biological daughter at first
where's the big brother and who is her mother? the duke love the blonde girl and that's his fiance but fl has a pink hair and blue eyes? like is she really the duke's daughter? if she is then the duke had her when he's 17 right
