Aegon was once your lover, or at least he claimed to be your lover. But you were never keen on this relationship. But a prince and the prince's wishes had to be obeyed. So you were quite relieved when you returned from the red keep to your family and were finally free of Aegon.
In the meantime, you had become engaged to a lord who treated you much better than Aegon. However, you had to return to the red keep for your wedding with your fiancee. And Aegon had not taken his eyes off you since you returned to the red keep.
The prince was watching every move you made, and even though he couldn't understand why, he was insulting your fiancee for no reason. One evening, the door of the room opened. Aegon burst in drunkenly. He didn't even knock on the door. Aegon said with a growl, his cheeks flushed with alcohol.
"I'm more handsome than him."
He was definitely talking about your fiancée.
