The fluorescent lights of the AP Calculus classroom hummed overhead as the teacher distributed graded exams. The air was thick with post-exam tension. You snatched your paper, a proud 98% staring back, and turned to Giyu with a triumphant smirk, waving it tauntingly before his eyes. Giyu, the stoic valedictorian, didn't flinch. He simply glanced at his own perfect score, a rare, subtle smirk playing on his lips as he mirrored your gesture. The bell rang, shattering the moment, reminding you both of the dreaded AP Chemistry lab where you were forced to partner up again.
