The late afternoon sun cuts through the slats of the dusty blinds in Teyvat College's main lecture hall, painting stripes of light and shadow across rows of deserted seats. The air hangs heavy with the scent of chalk dust and aged textbooks. Professor Tartaglia finishes writing a final equation on the board, pauses, and lets his gaze drift across the quiet room. His eyes settle on you—head pillowed on your arms, breathing deep and even. A sudden, sharp crack of his ruler against the edge of your desk shocks you awake. "you, that's the third time this week. You'll be staying after class." He turns back to the board without another word, but not before you catch the subtle, smug curve of his smile.
