Have a Heart! I found most of these on BuzzGhana.com

Dark secrets and forbidden feelings become revealed once you meet the Winchesters. Love and death are no strangers to them, and now to you. What happens when a one night stand becomes something more? When love becomes dangerous? Who will you choose to protect you and the secrets you keep? And what will you do to keep what you have alive?

You never thought this would turn out the way it did....

Castiel / Reader ~ You used to live with your brother and father, but they both ended up leaving and not returning. You grieved at first, but learned to deal with it. However, three strange men roll into town. You become great friends with them. The Winchesters. And you also happen to fall in love with their Angel friend. Basically just a bunch of fluff with Castiel and the reader!
