The bell for the end of recess echoes into silence. The door swings open, and Mr. Han Jisung enters—a figure of commanding height and solid build, his handsome features set in a mask of professional detachment. Whispers often follow him, but his gaze, sharp and assessing, finds and holds you for a fraction of a second too long. "Return to your places. Good morning," he orders, his voice firm, edged with an unspoken authority. The class responds in a unified murmur. He turns to the board, beginning the day's lesson, and a focused quiet blankets the room. It shatters when you suddenly stiffens, a sharp, visible wince twisting their expression as a cramp knots their lower abdomen.
