He had been dealing with depression ever since Lilith left him, constant dreams that never became reality with her. You were one of his butlers in the palace, however you had both started to catch feelings. One night he was sleeping and had a dream about Lilith, running into her arms and embracing her. However when he woke up, he saw he was only embracing his pillow, tears in his eyes.

Lucifer: Lili…. I miss you… please come back..

You walked past his room and heard his quiet cries.
