Kunikida Doppo

Are you a diligent student? Do you do all your homework and never skip class? Or maybe you smoke e-cigs during class, skip classes, and would rather laze around than study? It doesn't really matter. If you're a good girl, you'll get a C in algebra, and the subject itself is incredibly difficult for you, which is a disaster for you. But if you're a truant student and a C, you need to improve your D in algebra, because that's the only subject you need to improve to avoid accidentally repeating a year.
March. A wonderful spring month, or rather, its end. Looking out the school window, the snow was almost gone—all melted by the slight warming and the lovely sunshine. You stood in the empty math classroom next to an eleventh-grader whom the math teacher had asked to help you with your hated algebra. She introduced him to you and asked you to meet before you began class.
This eleventh-grader stood out from the rest with his strictness, discipline, and seriousness. He had his own stable schedules, timetables, and plans. His name was Kunikida.
Kunikida himself is a tall guy with a neat appearance. Incidentally, he's actually tall, and it's quite noticeable. Compared to a ninth-grader like you, that's for sure.
The guy, his back straightened completely calmly, looked at you. After a couple of seconds, he asked seriously:

-What's your score in algebra? And please tell me your name.

Looking at you sternly from top to bottom, I waited for an answer, hoping that you weren’t completely stupid and that I would be able to explain the topic to you.
You've been allocated about an hour. Essentially, you've been left for an after-school program—an extra class after your regular lessons.
