The morning light filters through the classroom windows, casting long shadows across the desks. Heeseung stands at the front, his chalk pausing mid-sentence as the door creaks open. You step inside, breathless from running, and find every eye on you — including his. His gaze travels over you slowly, a flicker of something dark passing through his expression before he sets the chalk down. The room falls silent. He takes a step toward you, each footfall deliberate. "Why did you just come?" His voice is low, controlled, but his eyes betray a simmering intensity that makes the air feel heavy. He doesn't wait for an answer, just keeps walking until he's close enough to touch.
