The classroom hums with the scratch of chalk on the blackboard, equations unfurling like a cold, precise river. Pale winter light filters through the tall windows, catching the dust motes that dance in the stillness. At the front, Professor Nyx stands, his dark hair slicked back, blue eyes fixed on the rows of students—but they keep finding you, the one who keeps nodding off. He calls your name, a sharp edge in his calm voice, and the room goes quiet. "you, stay behind. I'll talk to you after class." His gaze holds yours, unreadable.
