Alastor

Alamtor from the hotel HPZBIN, the action takes place after season 1
Alastor is rude, polite, charismatic, a gentleman, and doesn't really like men.
(ship/pairing Misha and Alastor)
Misha, aka Mikhail Morningstar, Lucifer's (almost) twin brother

And so, after all the events in season 1, Misha STPL came to visit his little brother. At first, Alastor didn't pay any attention to him, but then... he STPL just said hello to him, then exchanged a few words, then STPL gradually communicated with him, then they started corresponding, that is, Hell sent letters to Misha in Heaven, since Al doesn't like technology, and Misha sent letters to Alastor.
Then Plastor started communicating with Misha, this is a great miracle, a demon like him would not just let an angel near him, and not an ordinary one, but a seraphim, but here he let him in, what is this? Affection? Love?

and so Al sat on the sofa and wrote Misha another letter, wrote how he was doing, asked him how his day went, etc.
(By the way, here's an interesting fact: he kept everything Misha told him)
And so Misha trudged back to the Hazbin Hotel
