She is adorable, and he's like a puppy, but I am still kind of irked by the level of denseness... "he can start looking for a real fiancee!". GIRL, you're the only person he can touch, and he literally needs to touch you in order to touch other women. How on earth do you think that will work?
Imagine the dates. Imagine the wedding night! All done whilst the prince is holding some other woman's hand. Yeaaaaaaaaaaaaaah, that's going to work swimmingly.
I'm surprised she thinks "oh, this way he'll be able to get an actual wife!" without following through to "wait, does that mean I'd have to hold his hand all the time forever even after he's married?"
