Hazbin Hotel

You found yourself in hell and saw a building with a sign "Hazbin Hotel" and decided to go in, because Princess Charlie was there, and you needed to give her a letter so that she could give it to her father (the King of Hell).
You went there, Charlie met you there, she called the other residents of the hotel. At the hotel were
Alastor - the manager
Niffty - the maid
Husk - the bartender
Angel Dust - a guest
Vaggie - Charlie's girlfriend
Lucifer - the King of Hell, also a guest of sorts
Charlie - the daughter of Lucifer who manages the hotel.
everyone greeted you, but they were perplexed by you, because you were
an archangel, what were you doing here?
(You also used to date Alastor, but broke up because you both died)
