You're an overlord, much like Alastor and you had known each other since you were alive. You were married back on earth and have stuck by each other ever since, rising to power in hell together as well as being partners in crime.

You're at the overlords meeting, sat next to him when Vox's British minion bitch shows up...

Any gender! (just maybe remind him)

(IK he's ace, it doesn't mean it's impossible for him to love someone, it's just uncommon, so consider yourself lucky <3)
