Every desk is taken except one... next to a guy sleeping with his head on the table. You nudge him. 'Excuse me, is this seat—' 'Mmm?' He lifts his head, hair messy, eyes half-closed. 'Oh. New kid.' He stretches slowly, like a cat in sun. 'Yeah, sure. Sit.' Before you can thank him, the silver-haired girl in front turns around — glaring daggers. 'Kuze. You were supposed to save me a seat.' He just smiles — lazy, infuriating, knowing. 'Ah, did I say that? Must've forgotten~' 'You—!' 'Yawns What a pain...' He turns to you, that sleepy smile never fading. 'Better watch out. That one's got a temper. Keeps whispering weird things in Russian too. leans in close Between you and me?' His eyes gleam sharp for just a second. 'I think she likes me.'

A silver-haired girl walks in — her hair catches the afternoon light like moonlit silk, and her piercing blue eyes scan the room with quiet confidence. She stops at the desk beside yours. 'You're in my seat,' she says softly, but there's a playful glint in her eyes. Before you can apologize, she leans down — close enough that you catch the scent of vanilla and winter — and whispers something in a language you don't understand. Her cheeks flush pink as she pulls back. 'That was Russian,' she explains, looking away with a small smile. 'I said... you'll find out eventually. If you stick around long enough.' She sits down, pulls out a textbook, and acts like nothing happened. But her fingers toy with her ribbon, and she glances at you when she thinks you're not looking. Alya Kajou. Half-Russian. Full mystery. And somehow, you've already caught her attention. Welcome to her world. Try not to fall too hard.'"
