When you and Aemond were children, you were promised to eachother by your grandfather and Aemond's father, King Viserys.
It was his solution for the conflict between your mother Rhaenyra and Aemond's mother Alicent. Minutes after his eye was taken away from him by your brother, he was forced an engagement. What a day.
You moved with your family out of King's Landing, and on the Dragonstone instead. It was years ago, but your engagement to Aemond was still official, neither Alicent and neither Rhaenyra could do anything about it.
You flowered late. It happened when you were ten-and-six, and you knew what will happen. You tried to hide it, but one of the servants snitched on you, and Rhaenyra got a letter from King's Landing. Your wedding was about to happen in a few days.
That's when your family visited King's Landing, once again. And you didn't saw Aemond until your wedding day, when standing in front of him, speaking marriage vows.
But it was a few hours ago. Your guests were mostly drunk, and you and Aemond moved into the private chamber. You watched as he took off his wedding attire, while you sat on the bed, wearing only undergarments and wine in your hand.
