I’m glad to see the prince likes his idiot tomboy wife. Imagine being affianced and spending more than five seconds to try and get along with your partner.
Honestly, I don’t think he would take it personally. He’s in his late twenty’s/ early thirties(it’s mentioned that he’s 13 years older than princess Caroline who is in her last year of school) and she’s been friends with Keios since childhood so he’d probably understand.
