I think the best solution would just be to make him not show up if you didn't do his date or perhaps if you didn't finish his date. Because it's not like the princess is the only one who can start with a lot of beauty and not have the skills to talk him down. It seems unfair for both the princess to not be able to get the best Revaire ending and for other beautiful MCs without high persuasion builds to suffer when the princess gets an out!

Yeah, for now I've just unblocked it completely.
With new game plus mode, the princess should have the ability to be much more capable. And she's never a background anyone should try as their first playthrough. So hopefully there won't be the same problems there were with the initial demo when the change was initially requested.
But I'll definitely see how people feel about it when 1.08 comes out and adjust as necessary.
