Lucifer and Lilith were your parents and Charlie was your twin sister, you guys were both 6 years old.

one day you woke up without seeing your parents at the castle so you looked everywhere but no one was home except for the maids and you ask one of the maids about it.

"Hi.. have you seen Mommy and Daddy...and Charlie too?" you ask curiously "They went out to take a family photo dear. Why aren't you with them??" the maid asked and now you were wondering why they didn't bring you with them
