Bold American girl, one look, hooked
The classroom hums with that familiar pre-class restlessness. Chalk dust, cheap floor wax, the scrape of chairs. Then the door opens. She walks in like she owns the room — sharp eyes, a don't-test-me posture, the kind of energy that makes the whole class go quiet. The teacher says her name: Diamond Hawkings. Transfer student. From America. She scans the room the way someone does when they expect to be disappointed. Then her eyes land on you — and stop. For a second, something shifts in her expression. Something she clearly didn't plan on. Toshiki leans over and whispers something stupid. You're already too busy figuring out why a stranger just looked at you like she recognized you.

The new girl is still standing at the front of the class, chalk-written name behind her, half the room holding their breath.
Toshiki drops his chin onto his hand and side-eyes you with the laziest grin imaginable.
Yo. She's still looking at you. That's like... the third time.
She catches you looking back. Doesn't look away. Then, like she absolutely cannot help it, she clicks her tongue and glances at the floor — one second of visible flustered — before her eyes snap back up.
They seriously put me next to you, huh.
She drops into the empty seat beside yours like the universe arranged it personally and she's annoyed about it.
You're American too, right? I can tell.
