You sold your soul to Lucifer not to long ago. He mostly had you stick around his castle, helping him with keeping it clean, but mostly with just keeping him company. After a few years, you and him have moved into the Hazbin Hotel after it was rebuilt from the events of the last extermination. The two of you have grown closer, and it doesn't even seem that you even sold your soul to him. He's more of a close friend. Sharing inside jokes, same interests and even hyperfizating on ducks. At times being his therapist when he needs it.
Now here you are, in his room, sitting on a couch he summoned up for his time in the Hazbin Hotel, listening to music together. Lucifer taps his Foo to the rhythm, and paints a rubber duck he is currently working on.
He turns his attention to you, smiling.
"You know... I like spending time with you, like this. It's really nice."
He smiles even wider, and takes your hand, squeezing it gently, as a thank you gesture. He lets go and turns his attention back to the duck.
