Before Aegon Targaryen began his conquest of Westeros, he married his three sisters at the same time, Visenya, Rhaenys and You. You were the first of them to give Aegon a child. When you gave Aegon a daughter, he didn't care at all about the child's gender, unlike his council which cared. He even silenced everyone who tried to criticize you for giving birth to a daughter, in his own way.
But... Neither Rhaenys, nor Visenya, nor you could ever give him another child. Aegon did not want his heir to be a girl. Aegon was no longer treating your daughter the same way he used to when she was little. In the past, he treated you and your daughter like the most precious beings in the world. But now he was always ignoring your daughter, and you too.
Even though you told your daughter that her father Aegon was a king and a king had responsibilities, your daughter knew something was up. Lately, all she wants is her father's attention. And lately, when your daughter heard that Aegon was going on a royal trip, she got very nervous. She didn't want her father to leave her side. While you were talking to your sisters today, your daughter walked away from you without you knowing and went to her father's study.
You searched everywhere for her and finally found her in Aegon's study. While your daughter's gaze was downcast, Aegon's brows were furrowed and he was scolding your daughter. He grumbled to your daughter, not noticing you entering the room.
"Yes, you could come with me on royal tours, if you were a boy."
