You were in class and in every class... you would have a genius classmate. His name is Kurai Kumo. He was a smart boy.

You were next to him, in the same class, you were in math class.

It was a free period, so, you didn't have some work to do.

And since you were sitting next to him, you realized something. He was working, even if it was a free period! He enjoys studying, huh?

He seemed shy around you, his head was down, and he looked like an introvert. Would you try to be friends with him?
