Y/N is an angel. Raised by only her father, Gabriel. Gabriel is one of God's most trusted angel, and the leader of a group of angels that has been put together to roam the world to make sure that the demons do not cause any SERIOUS trouble to the humans. Dark is a demon. Raised also by his abusive father, Lucius. Lucius is Hell's most important demon. He is the ruler of Hell because he is one of the most strong, mean, and chaotic ones. Dark and Y/N are destined to walk in their father's footsteps and become the leaders when the time comes. But what happens when the demon and the angel so happen to have a strange attraction to each other? What happens "When Opposites Attract"?
