Y/n is an ancient vampire. For the past 200 and something years, she’s been living in a cottage in the woods. No one knew she was there. Or so she thought. One night, her cottage was lit on fire, and she barely made it out of there. Not long after, The Avengers arrived to put out the fire. They saw Y/n and brought her back to the tower, not knowing yet that she was a vampire. Y/n normally didn’t trust easily, but somehow, it didn’t take her long to trust Bucky. And not long after, the others too. Though, not everyone wanted her to be safe. Hydra… they had found out about her. And they wanted her.
