Happy extermination

If you are reading this then you watch Hazbin hotel and you ship Alastor and Rosie. I've tried looking for a Alastor x Rosie story but I couldn't find one so I decided to make one. Before we begin I have to mention that I will be adding characters that will never be in Hazbin hotel because I made them up but we'll talk about them later. I should also mention that Charlie and Vaggie are not dating in this story Vaggie is single for now and Charlie is married to Sevithian she gave him a second chance and Angel and Husk are also dating so ya. Now let's begin.
