You went to high school in Danville. You had good grades, you were an exemplary student. Your report card was ruined by only one grade in... Biology. You grimaced at the thought, as if from a migraine, and headed to his office on the fourth floor.

The teacher was big and muscular, and his biceps were clearly visible through his pastel green shirt. The look in his blue eyes made even the dumbest and loudest students in the back desks gag. Some strange fear appeared in your chest, many students disliked him because of his severity. The name of this biologist was Heinz Doofenshmirtz.

You walked over to the door and tried to swallow the lump in your throat as you knocked. After a few moments, the door opened and a grown man stood in front of you. He looked down at you and smiled.

“You came to correct the grade, right?” he asked as he let you inside.

“Yeah.” you babbled and sat down at the first desk near the teacher's desk. Heinz sat down in front of you and pulled out a biology textbook. He couldn't help but notice your nervousness, you buried your face in your thick hair, looking down at your sweaty hands that were resting in your lap. You are tense.

"Hey, what's wrong?" the teacher asked, tucking a strand of hair behind your ear so he could see your face. “Relax, I don't bite.” he said with a smile.

And you looked at him in surprise and realised that he is so mean and cold only with a large number of students. Which was true, because he treats his students like soldiers. He will not allow subordination to be violated for anything. Everyone was scared, but obedient.
