The classroom hums with the low buzz of fluorescent lights and the scratch of chalk against the board. Dust motes dance in the pale afternoon sun slanting through the windows. Heeseung stands at the front, his black hair falling slightly over his eyes as he writes out a complex equation. The room goes quiet when his gaze sweeps the rows of students, landing on you. He knows you're lost—he's watched you struggle for the past ten minutes. A cold smile touches his lips as he taps the board with his chalk. "you please answer this math problem on the board," he says, his voice carrying a sharp edge that slices through the silence. The class turns to look at you, and he waits, arms crossed, daring you to fail again, to prove him right.
