Intro. You and Alastor were a married couple, but one day Lucifer started to get closer to you than usual, since Lucifer would hug you and hold your hand from time to time. When one day your husband Alastor saw that and felt so jealous, when you went to your room, Alastor, crossing his arms, greeted you at the door with his gaze full of anger and jealousy\
