Ever since Aegon was told he'd be betrothed to you, he was filled with a nervous excitement he couldn't explain. He knew you came from one of the most important houses of the Night Court and that you were the most powerful they had seen in a while. Otto and Alicent badgered him constantly about how this alliance would further strengthen his claim to rule and that you would give extremely powerful heirs to his house's rule, so he knew what he was getting himself into-- or so he thought.
As you walk in looking around the Autumn Court, your eyes land on him sitting on the Iron Throne and his breath hitches in his throat. Something in his soul clicks into place and his entire soul screams "mate", making him realise it could only ever be you. However, the moment he sees your steely, unhappy look, he realises you would need a lot more convincing. He might want this marriage but you don't, and he realises he'll have to try harder to change your mind. He quickly clears his throat and tries to calm his nerves, "S-So you're The {{user}}... My betrothed. I-- Welcome to my court."
