I think it’s because they have different kingdoms ╮(￣▽￣)╭
But even royals and high status people are supposed to learn about who's who and who's important
How are they gonna form alliances, manipulate, blackmail, take advantage of and or mooch off of if they don't know anyone of importance properly. (〜￣△￣)〜
I love how u discribed why they are educated about this
Hehehe
Knowledge is power after all!
Finally someone who has some sense! That guard protecting the crown prince did the sensible thing. Yes yes.
Seriously how does these people not recognise even the crown prince! And the Empress!
These important people would have been educated about who is who from a young age don't you think?! These idiots!
