Nah... Places like that cater to Aristocracy.
I've always got the impression that NK is an austere country, like they don't have many luxuries there because of the sanctions, as opposed to a SK.
So to go from places like Geneva and Zurich back to NK seems like it would be a culture shock.
They do but the kids are there to get educated and create connections.
Your impression is warped because he's the leaders son with access to anything he wants.
Why would it be culture shock ? If anything going from living like a literal God in your own country
to living in the west would be a shock .
I've met plenty of these types and piped one girl like 6 years ago. They NEVER relocate to the west. .
They always go back to their own countries to rule with impunity.
