Angel With A Shotgun (Songfiction)

Ally is an Angel. No, literally. She came from Heaven! She came to Earth to keep an eye on her ex-best friend who's causing mischief, Alex, the Demon, and ex-Angel. Ally was told that if he does anything to harm anyone or their chances of coming to Heaven; to shoot him.
There is a war and Alex was chosen to go to the War. Because it would save him from an eternity in Hell. Sadly, Ally murdered someone accidentally and is now banned from Heaven. She doesn't want to tell Alex, but she is afraid he'll get killed in the war and they'll never see each other again. As much as she wants him to be happy in heaven, she doesn't want him to go to war. If she's going to Hell; she wants to be happy!
They are in Love.
