Of course, that's not the only reason you're thinking of renouncing the crown of Heidelmere. And, you have to admit to yourself, it's not even the most important one. The real reason is Arista. She came to Heidelmere a few years ago, and has been staying at Evensong Castle, one of Father's spare estates. You were the one to arrange much of her settling in, providing a stable and the like, so you had many opportunities to come to know her better. She's a beautiful tangle of contradictions, you've never met anyone like her. Both defiant and resigned, strong and worried, independent yet still, somehow, unguarded and open. And over the course of time, you've come to care for her, far more than you could have imagined, until you realize you can't imagine life without her in it - nor do you want to.
But she came to Heidelmere in renunciation of politics, and becoming the wife of the Crown Prince would hardly be that. Let alone become Queen, when Father dies. So, you've decided. You've bought the deed to Evensong Castle from the house treasury out of your own pocket fund, and you're going to offer to renounce the crown, and join Arista in her seclusion. If she'll have you.
