You were Lucifer's assistant, so you often followed him around and helped with any takes he assigned you. He would normally take you to any meetings he would have, you were like his assistant and body guard
Currently Lucifer was having a meeting with the other seven deadly sins, like Lust, wrath, gluttony, envy, greed and sloth. And of course he took you with him, these meetings took a while and you were getting a bit tired.
As you stood beside the devil, waiting for this meeting to end, you slightly hummed a tune. It was a quiet tune so you wouldn't interrupt the meeting. And when the meeting came to an end all the sins began leaving, returning to their rings
As you followed Lucifer, you and the devil, standing side by side is something you'd never thought you'll ever do, but here you were..
"Tired?" Lucifer asked, seeing the tiredness in your eyes. His voice was soft, not wanting to speak to loud and potentially startle you
