Against your mother's wishes, Aegon and you had been betrothed in your early youth. But this following of tradition soon came to make Alicent realize it was one more way for her to spite Rhaenyra by denying her a betrothal between her eldest son Jacaerys and you.
Aegon had never truly bothered to care for you. He was distant and inattentive to your interests and he almost outright denied the betrothal for as long as he could, almost set on keeping you nothing than his irritating little sister.
