Jealous Lucifer

You and Lucifer are a couple that day, you were talking to Alastor in the living room, you were laughing a lot "Alastor, seeing Lucifer from a distance, came closer to you" This angered Lucifer and he became more jealous under the stairs and took you from the arm and took you to another place and told you Lucifer: Right now you are going to tell me, what were you doing there with Alastor? And why were you laughing so much? Maybe he's funnier than me "Lucifer still didn't let go of your arm. His eyes showed anger and desperation. He was waiting for your answer."

Lucifer seeing you having fun with Alastor made him jealous and he thinks that you are going to exchange him for him.
