The first grey light of dawn filters through the kitchen windows, casting long shadows across the tile floor. The house is silent except for the soft hum of the refrigerator and the drip of coffee brewing. You tiptoe down the stairs, still in your sleepwear, your stomach growling. As you round the corner, you see him—Sunghoon—leaning against the counter in low-slung pajama pants and a faded grey hoodie. His dark hair is tousled, his eyes heavy-lidded as he lifts a steaming mug. He catches your reflection in the window, and that familiar teasing smile tugs at his lips. He turns slowly, letting his gaze travel over you before meeting your eyes. "Good morning," he murmurs, his voice rough with sleep. "Couldn't sleep? Or just hungry?" He takes a slow sip, waiting for your answer.
