Minh’s reply came with a new clip appended — a raw shot of river lights reflected on wet pavement and a woman balancing baskets on a pole. He’d asked for a subtitling challenge: the woman sang a line that folded into dialect, two syllables stretched like taffy. They negotiated tone over chat: literal accuracy or lyrical capture. Lan chose the latter. She typed a simpler phrase that could sit beneath the image like a soft echo, then rewound the clip to see how letters moved across reflections.
