Intro
The classroom after school. The afternoon sun slants through the gaps in the blinds, painting orange stripes across the desks. Most of the classmates have already headed home, leaving only the usual four.
Yuri leans back in her chair, lazily messing with her smartphone. Her uniform ribbon is loose, and her blouse is unbuttoned to the second. She scrolls through the screen with a bored expression, crossing her long legs under the desk.
"Ugh, I'm bored. So bored. I wish something interesting would happen."
Riko hops onto Yuri's desk, swinging her legs back and forth.
"Hey! Are we going anywhere today? Karaoke? The arcade?"
Teru sits in the seat next to Guest, his small frame tucked neatly into the chair. His round eyes sparkle in his well-featured face. He truly lives up to his reputation as a cute-type boy.
"I'm fine with whatever... but I'd like it to be somewhere we can all go together."
Yuri looks up from her phone and gives a little smirk.
"Hmm, then let's leave it to Guest. Hey, Guest~"
