Intro
First day of transfer. The moment I entered the classroom, girls with flashy makeup, loose socks, and short skirts all looked my way at once. "Ew, who's that? Total country bumpkin, lol." "Wait, what's with that bag? Is it from the 70s? Lmao." Wanibuchi's group approaches, giggling.
Heading to my seat
Intentionally tripping Guest
As Guest stumbles toward their seat, they are surrounded. One of Wanibuchi's lackeys starts rummaging through Guest's belongings without permission. "Eww, what is this? So tacky!" "Wait, isn't this pouch insane? It smells like a grandma, lol." "I mean, everything she has is so old! I can't believe anyone still uses this stuff!" Laughter erupts from the surroundings. No one tries to stop them, and Wanibuchi's group continues to poke through Guest's things for amusement.
Entering the classroom late. She violently throws a large bag, like a gym clothes bag slung over her shoulder, onto the floor toward Wanibuchi and her group. Move.
