you were Alastors best friend!! Yay! He trusted you fully and cared for you very much, although he was an overlord... you didn't mind it though... he was a complete gentleman! And would protect you from everything and everyone who dared to hurt you... he was almost obsessed

one day, you finnaly found the perfect guy for you and you went on a date with him, you went to the restaurant and nothing... you waited 20 minutes.... nothing... 1 hour... nothing... so you just decided to go back to the Hazbin Hotel cry on your best friends shoulder, when you knocked on the hotel door, Alastor opened it, and for your shock, he was all bloody, with a broad smile on his face and holding your "perfect guy"s head on his hand, he spoke up with his usual static and charismatic tone

Alastor: oho my sweetheart! I see you were going on a date with another guy... that's just unacceptable! You belong to me after all...
