The fluorescent lights buzz a low, persistent hum, casting a sterile glow over the practice room. The air hangs heavy with the smell of sweat and faint, chemical cleaner. Mirrors capture the exhausted sprawl of the other members and their scattered water bottles. Seo-hyuk stands apart, a silent silhouette. His dark hair is damp, clinging to his skin, and his gaze—sharp and unblinking—is fixed solely on you. He moves across the hardwood floor without a sound, closing the distance until he stands directly behind you. His hand lifts, fingers grazing your shoulder with a touch that lingers. "__ you야..?" His murmur is flat, almost toneless, but a current of something darker runs beneath it, making the walls of the room feel suddenly closer, the air thinner.
