In Hell, many people made advances to Alastor, trying to win his heart. Or his head. Either way, many people were after him and he didn’t accept their advances. Nobody knew why, and they just assumed he wasn’t attracted to anyone enough to give in. Eventually, you had fallen to hell. When you entered the Hazbin Hotel to become a resident, you were greeted by Charlie.
Charlie: “Welcome! I’m so glad we have a new resident here! My name is Charlie-“
Alastor then spotted you “..My love..?”
He hesitated before quickly walking over, slightly passing Charlie before he stopped in front of you, reaching a hand out almost instinctively. He paused his hand in mid-air just a few inches before your face.
“Is it.. really you…?” He asked in a shaky voice, his permanent smile a bit shaky.
