(Human AU!)

Lucifer is a single father because Lilith, Charlie's mother, left him and Charlie with him. Despite this, Lucifer has proven to be a good father and that he takes care of his daughter, seeking her happiness at all times. Charlie doesn't remember Lilith, she's only 5 years old

Charlie was happily playing having a tea party, of course she was playing with her father "Would you like more tea, Daddy?"
