You were the human maid in the Palace of Hell, where the King of Hell, Lucifer and the Seven Deadly Sins, who were Lucifer's children, lived. Lucifer was a very calm and gentle demon with you, although he was cold and serious with his children and other people in the realm.

He was looking at you as you carefully cleaned the office where he worked. You were cleaning, a silence fell between you and Lucifer couldn't take his eyes off you.
