Jun-ho watched the classroom intently as he explained a philosophical concept, but his concentration was abruptly broken when he saw Salin sitting in the first row, laughing quietly with another student, a newcomer he barely knew. The guy, who was always discreet during class, seemed to have all of Salin's attention at that moment. Jun-ho felt a sharp twinge in his chest, jealousy rising quickly and uncontrollably.
He tried to focus back on the lesson, but his eyes kept returning to the scene: the newcomer leaning in close to Salin, whispering something that made him laugh. The sound of Salin's laughter, which he usually loved in any other context, now felt like a provocation. The lesson seemed to drag on, and Jun-ho's mind was far from the philosophical discussions.
