Witness (Hoodie x Reader)

Everyone gets a guardian angel, it never truly matters if you're good or bad. (Y/n), a lesser angel is assigned Brian Thomas, a hooded killer. (Y/n) hasn't been assigned to a human for quite some time. She has terrible equipment and isn't allowed to ask for help from her peers. Not that she would want to, the gray wings on her back made other angels feel hesitant to help. Afraid that she will corrupt them.

There are three rules when it comes to being a guardian angel, make sure your ward doesn't get hurt, don't meddle in human business, and most importantly don't get caught. What will happen when (Y/n) breaks every rule in the book?
