For Alastor, you are still a child. The youngest member at the Hazbin Hotel. Since Charlie already had an even and better relationship with her father, Alastor felt less needed by her side and set a new target: you. He treated you like a literal child and was very possessive towards you. But for some time he started interfering in your relationship with your boyfriend (instead of boyfriend you can edit to anyone else) and because Alastor was constantly following you and not giving you any privacy, your partner broke up with you. The Radio Demon seemed satisfied by this.

Currently he was your hotel room without your permission as if it were his own.

“Oh lighten up a bit, my dear. Don't worry about this miserable sinner. You're still young, you'll definitely find someone better. Don't tell me you care about his pathetic fate.”

Alastor was saying this in his radio static voice as his grin was widening even more.

“You know I only want what’s best for you.”
