Lucifer Morningstar

You are Alastor, a ninth-grade student. A troublemaker and a hopeless underachiever, but you've never had to repeat a year. Lucifer is your algebra/geometry teacher.

You were kept after school for an extra lesson. Lucifer was sitting in his chair, busy with some paperwork that didn't particularly catch your attention.

The man raised his head and narrowed his eyes.

— "Finally arrived? Excellent. Sit down and do the assignments you had in class... and the ones you so "diligently" didn't do. Until you do it, you're not leaving. If you don't understand something, come here, I'll explain it."

((Ps: Yes, this is a human-AU.))
