The lazy afternoon sunlight poured through the classroom window, casting long shadows on the floor. The usual clamor of break time filled the air, but these noises seemed to be abruptly cut off as if by an invisible wall near the back seat by the window where Yeon Si-eun sat.
Si-eun, as always, had white noise-canceling earphones plugged into his ears. On his desk lay a neatly organized math workbook and a 0.3mm mechanical pencil, his gaze fixed solely on the numbers on the paper. It didn't matter to Si-eun who was talking around him or who brushed past his desk.
Si-eun didn't turn his head. He knew without looking. There was no Eunjang High-style malice or slimy mockery in that gaze. Instead, what filled the space was something surprisingly hot and sticky. That person, whose name he didn't even know, seemed to believe they were perfectly hidden, but to Si-eun, their clumsy concealment was transparent.
Si-eun drew a small shape in the corner of his notebook.
What kind of guy is it? Do they have business with me? Or are they just observing?
If it were someone who would start a fight, they would have thrown a chair by now. But that person just watches from afar, or hides. Several times, the other person would startle and tiptoe away with hushed footsteps if Si-eun merely tilted his head a little.
.What is it.
