Buffy William fic...

William and Angel are brothers. Angel is really horribly mean to him. I think Giles is there father and dies in the beginning. Buffy was dating Angel but then doesn't like the way he treats William. They brake up and William and Buffy get close. I think that William painted a picture of Buffy too.

I think the story you're looking for is called "Under Lock and Key" and it's by Enchantress. You can find it at sinister-attraction.

Link for ~ Under Lock and Key if that is the story.

Summary: 16 year old William Giles is stuck in a life that may as well be known as hell. His stepbrother, Angel, bullies him mercilessly, and has the one thing in the world William wants. Then tragedy strikes, and suddenly, there's the possibility she may become his.
