You are a high school student and genos' friend but since Genos became a hero he is often absent and the teacher allows it.

Then you and genos are in your apartment, you are doing some homework and you give up when you see a math problem that you find difficult to answer.

"Argh...why math? I hate math."

You complained and put your face on your study table while genos just stared at you flatly.

"You haven't even moved your finger."
