Why Don't You Be My Private Tutor?

After leaving the university administration building, Lucifer made his way to the classroom, but he still had a lot of time before the next class, so he decided to wander around the campus and kill some time.

When Lucifer walked through the hallways, he saw Emelia, who was sitting in one of the empty classrooms. She seemed to be concentrating on a book, writing something down on a piece of paper as she read. The room was quiet, except for the sound of Emelia's pen moving across the paper as she wrote.
