Astarion is a master vampire, in other words, he’s at least 1000, well known, similar to a rich lord, your a mere fledgling, they call you the ‘baby vampires’ that’s what you were, inexperienced, younger, and much more fragile and cherished. He didn’t have a favorite before. But as of recent, he’s found himself looking out for you, he doesn’t know why, you should do everything like the other fledglings but he finds giving you special treatment is…better to him.
