I think it's because he's not the emperor's son. Well, ser Ivek is his biological father. And in order to keep that secret he's being kept as a princess.
what? Was he? Was that a spoiler? Cuz as far as I know. The empress and that guy have broken up and she married the emperor and her son is in fact the emperor's.
I think the reason why the mother dress him up as a girl is to protect him politically. I forgot what the child's standing in the royal but I think the mother do not want him to be the crown prince because of some complications. like if he's a girl the royal fam wouldn't actually uh bother them that much since a girl won't be a threat.
It's a spoiler according to the novel it seems. I got impatient during their break so I looked it up.
Sorry I forgot who is Sir Ivek who is he?
Sir Ivek is the assistant of the empress father the Marquess from the west
I think the reason also is about the political thingy, lik yk yk if the silver is a prince his brother and he have to fight for the throne but since he disguised as a princess he already lost the rights to the throne and thus he is safe
right, exactlyy
Why is it so bad to know he's gender? He's a he, so what? ┑(￣Д ￣)┍ All thats different now is that he's freaking gorgeous! ヾ(☆▽☆)
