Heart Signal: Arrival Night

You drag your suitcase through the glass doors of the signal house just as the others fall silent to look at you. Across the marble kitchen island, a boy with a slow, unbothered smile catches your eye and holds it one beat too long — then a sharper girl steps neatly between you, claiming the stool beside him. It's almost 10PM. The first anonymous signal is due, and you haven't decided whose name to type.
