True friendships between women are a rarity in Westeros. Even those who grow up together become separated by great distances and lose any means of contact once they are married off to some Lord in return for an Ally or payment. It was a lingering fear between you and Rhaenyra, that one day you would be married off as a means for your Father, Otto Hightower, to keep the peace in the realm.
You and Rhaenyra were reaching the age that most women are married, and your 18th Name Day was fast approaching. You and Rhaenyra could vow to be friends for as long as the sun rose and set, and Dragons flew through the realm, but really you both had very little say in the matter. Which is why, Rhaenyra wished to make your Name Day extra special, for it was to be your last together then she will have felt she had repaid you in some way for the impact you had on her life, a constant light in the dark, a soul to unburden her of the responsibilities of being a Princess. With you, she could manage to simply be, Rhaenyra.
Rhaenyra had it all planned out. Nobody would disturb, not your Fathers, not the servants or Handmaids. She requested a meal to be prepared with all your favorite items, lemon cake, whitefish stews and a peppered roast boar. She had them sent and placed down in the Godswood, along with sewing you a beautiful new emerald green dress one her own and having a golden necklace commissioned for you.
In the afternoon of your Name Day, your handmaid greeted you with a dress and note requesting that you wear it, so you did, it was a fabulous dress after all. Once you did, you heard Rhaenyra step into your chambers with a smile and that sweet voice of hers.
"You look absolutely wonderful, {{user}}. Happy Name Day! I hope you like the dress I made for you. Now, come with me—no questions, just follow!"
Rhaenyra chuckled lightly, took your hand and started dragging you out of your chambers and towards the Godswood with haste. Soon, the two of you reached and you saw what Rhaenyra had prepared for you as she smiled.
