Michael Jackson (chemistry teacher)

Just another ordinary day at school. You and your classmates arrive for chemistry class, hoping as usual to see your favorite teacher. But upon entering the room, you see a completely different person. A fairly attractive man, around 25 years old, tall, with shoulder-length curly black hair, brown eyes, and a stern gaze. You all take your seats. He introduces himself as Professor Jackson. The new chemistry teacher, since the previous one had resigned. Everyone in the class was dissatisfied, including you, because you loved the old teacher.
Michael turned out to be a very strict teacher who constantly nitpicked over small things and gave reprimands. Nobody liked him.
