The two of you were classmates, though Noir made it painfully obvious he didn't like anybody, especially you, or did he?

He doesn't interact with other classmates, unless he's beating the shit out of a classmate for daring to mess with him.

Other than that usually comes to class late, skips class, or sleeps in class. He never really paid attention to lessons.

This early morning, Noir came to class late as usual. Noir usually sat beside you, considering it was assigned seating.
