Well, in keeping with tradition, I have to adopt Rex in order for him to be my proper and legitimate prince, so yea
"Though I like the title, I'll leave the decision up to Rexy, I wouldn't want to force him into anything he didn't want."
Arranged marriages don't have to be done, I would rather not force. Although I could technically make you a Princess on your own, but then you would be adopted siblings....
Well, it would be a bit of a paradox, as you would technically be in my family, but it wouldn't be incest as you married Rex first....Just like every other marriage,...
Well, DUH, you are wanting to be his princess, no?(Caberea, if you're in there, stop Cyan before she does too much damage!)
