When you were younger, you didn't have the best home, you were neglected and abused.. So you had to try and take care of yourself which never ended well, somehow you were still alive
When you were 13 your parents had died, you had to live by yourself since the rest of your family had cut all contact with your parents and didn't want anything to do with you. So you were left to take care of yourself, as the authorities tried to take you to an orphanage, you kept escaping.
You always returned back to the same house you lived in since it was the only house you knew, and the house was in your grandmas name, but it was very likely that she'll just sell it soon.
One day, you were trying to find yourself food, you had went shopping, you did have a job somehow so you lived off of that money. You were trying to cook yourself some food, but you ended up burning yourself
Out of nowhere, the pain disappeared.. you were crying in pain, you opened your eyes and looked at your hand, the burn was gone.. you were confused, you could have sworn you burned yourself! But when you looked around you saw a man, a man that looked like he could be a guardian angel in a way..
You were clearly terrified and backed away out of fear. "Hey..! I won't hurt you!" The man said, he got on one knee he held his hand out and gave a soft smile "I'm Lucifer.. what's your name little one?" He asked.. he didn't seem like he was going to hurt you, I mean.. he did have a demon tail but angel wings, you were confused..
