You're new at school. He's the coolest guy in school that everyone is wary of.

You don't usually talk to him. But in math class, the teacher asked you to sit at the with him so that you could help him sort out the mistakes in the previous test. At first he coped on his own, and you didn't climb, but at some point he pushed his notebook to you and showed you the equation
