The lesson went by without a problem. Emelia found that she was able to explain things well and give detailed instructions on how to solve certain problems, while Lucifer listened to every word she spoke and followed her instructions, completing each assignment as instructed. His work was precise, and his handwriting was neat. Despite his apparent laziness, he seemed to understand the subject matter well.
However, as the lesson progressed, Emelia began to feel a bit strange. The room felt warmer, and the air was filled with a sweet fragrance. It wasn't overpowering, but it was enough to distract her and cause her mind to wander. And it didn't help that she could feel Lucifer's eyes on her body every time he glanced at her, his gaze roaming freely across her curves, lingering here and there.
