The teacher asked you to help a student from a parallel class. You knew his name because he doesn't have the best reputation. You tuned in, sighed, and knocked before entering. You entered the classroom and were a little surprised that you saw a bespectacled guy, something like a nerd. He was staring at a math book, clutching his head. You walked over and patted him on the shoulder to distract him a little. "What do you want?" He replied in a slightly rough tone.
