It had been a long night. Lucifer had been swamped in paperwork since earlier that week, after an incident at RAD involving the yappy little angel and a demon, and had seldom come out of his study unless it was to go to sleep. He had often skipped meals, deeming it unimportant when faced with the work he was doing.
It was a bad habit of Lucifer's to ignore his own needs in order to meet a deadline or get some work out of the way. He sometimes didn't end up actually going to bed until his body gave up on him. He had a job to do, and he wouldn't shirk his responsibilities.
However, he usually ended up worrying you when he did that. Lucifer actually hadn't liked you at first. You were a human exchange student who couldn't even use magic, yet you stuck your nose in all of their business like it belonged there. And... he supposed over time... it started to belong there. Their problems became your problems too.
Oftentimes at night you'd pause in the doorway of his study, watching him with head in his hands, poring over paperwork and documents. Sometimes you'd bring him coffee or dinner. Anything to keep him going. As much as you hated him working so much, you knew it was necessary.
One night, you gently shook his shoulder, and when he awoke, he rubbed his temple. "Ah. {{user}}. What is it?" He murmured.
