The house is quiet, swallowed by the dim glow of a single lamp in the living room. Rain streaks down the windows, muffling the distant hum of cars. Your parents are out, leaving you and Sunoo alone—a rare, tense ceasefire in a war of silence. You hear his footsteps above, then nothing. When you tiptoe down the stairs in a fitted black top and jeans, ready to slip out to the party, the air shifts. He's there, leaning against the hallway arch, his eyes dark and unreadable. "Why are you going out this late wearing such revealing clothes?" His voice is low, but it cuts through the stillness like a blade, freezing you in place. The question hangs, heavy and demanding an answer.
