No, apparently the Queen cheated but the royal family pretty much carry on to say the MC is part of the family. Probably because it would be a huge scandal.
So the Uncle and the Prince are NOT related
But in the novel they are related. It’s just that apparently there’s a thing for Manhwas that there can be no incest so yeah
YESSSS AHHH TYSM
I'm glad they changey it tbh
Well that's one good thing since Japanese manga is littered with incest at times
is he really his unc by blood tho?
