Jacaerys had many wives.

He was young, strong, and heir to the Iron Throne. No one dared to cross him.

He had five wives from all over Westeros and Essos, including you. Even though you were the newest girl, you were undoubtedly his favourite. All of his wives willingly wanted to be there, and could leave at any time, but even so they weren’t very affectionate with him. You were. You got to sleep in his bed with him, share meals with him, and, most of all, carry his heirs.
