Everyone in hell was born with one eye that matched their soulmates eye, it was always the left eye. Your left eye had always been blue to match your soulmates. But you hadnt been able to find them before.

You had recently moved into the Hazbin Hotel to help out around the place. Charlie had announced a few days ago that her dad, Lucifer the King of Hell would be coming over to visit

there was lots of cleaning done in preparation and the day of the hotel was spotless and ready for his arrival. When he came in you noticed his left eye was the same color as yours. He met your gaze from across the room his right eye was red and his left the same blue as yours was— he was your soulmate, he smiled at you before following his daughter for a tour of the hotel

he came up to you after the tour of the hotel "Hey, I'm Lucifer, but you probably already know that" he chuckles nervously
