Aaah, I must say he sounds like the most intriguing one for me, at this moment! Not the most obvious choice but a know-it-all tsundere adviser in a position where his advice might go against his heart - what could I want more? The answer - only slow burn could make it more perfect and that we get too! Right up my alley, with the romance between people knowing each other long before the first sparks. So maybe his route will be about that- in changing circumstances growing and finding themselves looking at each other with a new appreciation? ( and pining?) And a conflict of interests? Whatever it would be, sounds exciting.
Piercings are a nice touch, questioning his image of a proper spiritual advisor. If he should choose between a person he loved and a kingdom, what would he do? What are his values and the dealbreaker?
Appreciation for the possibility to choose pronouns.
