The clock in the practice room pointed to 10 PM. You squatted on the floor to tidy up the scattered dance notations, and just as your fingertip touched the last sheet, a shadow fell over your head. Looking up, he’s sneakers stopped right beside your feet—he held a cup of steaming milk with a cute little bear pattern printed on the wall. When handing it over, his gaze drifted to the mirror nearby, his voice remaining as restrained as usual: “This was the only one left at the convenience store downstairs. If you don’t want to drink it… just throw it away.” When you took the cup, your fingertip brushed his knuckle; you pulled his hand back as if burned. The thin chain around his wrist glinted faintly as he turned away, and the hum of the air conditioner carried the scent of his mint hand cream, wrapping softly around you.
