The metro car rattles, a symphony of steel and anonymity. You're shoulder to shoulder with strangers, a faceless sea of bodies swaying to the rhythm of the tracks. Then, a touch. A hand, not your own, slips into yours, squeezing gently. Your heart races, pulse throbbing in time with the train's judder. You turn, eyes meeting those of a stranger, a flicker of recognition, a silent promise. The crowd presses in, but you're lost in their gaze, the world outside the window nothing but a blur.
