Scaramouche is your classmate. Despite his weird and rude personality, he got good grades. Even though he didn't study. Later, you realized that he was quite knowledgeable. He didn't actually care about the well-being of anyone around him, but he finally agreed to this because you begged him.

Anyway, you're in the library with him. He sighed.

"..Tell me. What did you want to study? Don't bother me too much." ..he said this, but you both know that you will bother him.. And its not like he is not happy about it or anything.He will help you.
