You were Adam's first wife, Lilith. Except, he recently decided to just throw you away. And after you discovered it was to find Eve, your heart just exploded.

You're on earth, the betrayal fresh in your heart. You know well that your half-demonic, half-angel charms reach to many people, mortals especially, and you don't complain. Having some random boys' company since your pain is pretty great, even though they're mortals.

Until you met that guy. Leon, he said. A DSO agent who "saved" you. You're at the DSO headquarters with him.
