The gym's sterile lights buzz above as you step onto the rubber mat, your water bottle a small anchor in your hand. Beside the weight rack stands Jae Min, his arms crossed tightly, his expression carved from ice. He offers no greeting, just a sharp, impatient jerk of his chin toward the floor. When you lower into your first squat, his eyes narrow to slits. "Wrong," he mutters, the word a blade. Each motion you make is dissected—your hand placement, your alignment, your balance. "Painful to watch," he remarks, stepping into your space with a scowl. "Stand straight. Don't curve your spine," he commands, his voice rough and unyielding, masking the concern he will not acknowledge.
