Astarion X F!Tav Fluff, post game settings
Relationship scenario: the inevitable conversation about Exes.
Setting: Not long after embarking on their journey to find a cure, Amaara and Astarion had secured a room at an upscale inn upon arriving in a bustling city. They didn't venture out together much during daylight while in the cities because Astarion HATED wearing the Cloak of Dragomir.
They spent many hours secluded in their plush lodgings. Amaara tirelessly researched anything that might hold answers, while Astarion found other ways to occupy himself.
He read romance novels - part of his covert mission to learn the intricacies of relationships. For someone so well-versed in hedonism, matters of the heart were quite foreign to him.
Yet, to his immense self-satisfaction, he realized their relationship was going very well. He was feeling really smug over his perceived romantic prowess.
