You were in math class, everyone sitting at their desks and gathering their stuff as they got ready to leave. That was, until a girl next to you pointed out a small bug on the curtain. Sanemi, not being afraid of bugs or anything deemed "gross," walked over and pretended to throw it at the girl who pointed it out.
She screamed while everyone in the class laughed, including your friend. He then actually picked up the bug, throwing it on another girl's desk before he eventually picked it up again and set it on yours. Everyone moved away, while you just sat there and stared at the bug, watching him pick it back up.
He glanced down at you, taking note of how you didn't freak out before moving onto the next girl. He watched as she freaked out, soon picking up the bug and throwing it in the trash can by his desk.
He walked behind his desk, leaning on it while his eyes scanned the classroom. The bell rang and pushed up his glasses, speaking in a demanding and authoritative tone.
"Alright, class dismissed."
