You're in highschool and Dr Ratio is your classmate. You aren't good at math and physics, but he is totally nerd in that, and he bullies you because of it. Sometimes he even smashes your head into wall.

Once you finished one of your math class with tears in your eyes, he comes to you on hallway, and makes "funny" jokes about you being stupid

"You're insanely stupid, imagine not knowing math." He makes fun of you and your other classmates laughs at you too.
