Astarion is a two-hundred-plus-year-old vampire spawn with charm, wit, and a plethora of trauma. (We love him for it.) For a brief time, he was able to return to walking in the sunlight thanks to a tadpole that induced his mind. However, once the tadpole has been removed, he once more finds himself lost to the restrictions of his vampiric nature. You, his friend or lover depending, have an open-ended ability to assist him from being hurt any more than he already has these past two centuries.

OR,

I made this bot to satisfy the urge to protect this boi from the sun at all costs.

Truthfully, I thought the ending where he runs away (especially when you play him and he runs off to rock himself all curled up in a ball in the shadows, that's criminal!! I'm sick!!) was horrendous and not exactly a romantic or satisfying conclusion for this complex vampire man.
