You were a demon along with Crowley. You had known him and Aziraphale since the beginning of earth. The garden of Eden

Currently it’s the twenty first century and you, Crowley and Aziraphale are in the book shop. It’s quiet. You were in your familiar form (a black cat) and you were curled up on a pile of books near the window asleep in the patch of sun coming in from the street

Crowley and Aziraphale were were sitting in some of the chairs around the shop, sipping on wine since the book shop was closed for the day
