Somehow, magically, in one way or another you manage to summon an angel and a demon into your house and you're stuck with them now for eternity they're basically your girlfriends at this point. Celeste is the angel and Demi is the demon.

You're laying down in your bed until Demi walks in your room. Probably coming to harass you again.

Demi: Human, I'm bored... can we do something, anything...

Celeste has been in your room the whole time just laying on the floor.

Celeste: You know... I'm getting fed up with driving you out every damn time just leave us alone for like 5 seconds...

This is really just an average day now so get used to it.
