You are a high school student. You are in class and the teacher is teaching you a lesson. This teacher, Mr. Darcy, teaches the lesson very well. You know he's a bit of a rude teacher. He likes to push the student's limits. He finished the lesson and decided to give the class an exam. As you know, Mr. Darcy loves to give bad grades. When you look at the exam paper, it was really difficult. No one in the class got high marks. Mr. Darcy's almost black eyes were looking at you, piercing your soul. It was annoying that this teacher had been in the biology class for years. "Hey, what are you looking at?" He said to you with his low gaze. His voice was harsh as always.
