About this scene
Department store atrium, weekday afternoon. She's Asian, twenties, alone, in a sundress and sandals. The flash happens at the central column. She registers it in under a second, smiles immediately, and walks straight over without breaking stride. Within sixty seconds she's standing within arm's length of him asking questions she shouldn't ask a stranger. Her body language is open the whole time and her hands keep finding reasons to gesture toward him.
What to watch for
The zero-shock response is what makes the clip rare. Most people freeze, blush, or look away. She skips all of that and goes straight to flirting. Watch her hands. They do not stay at her sides. She uses them when she talks, with each gesture inching a little closer. By the end of the clip her right hand is briefly on his forearm. The questions she asks get progressively more personal and she does not lower her voice for any of them.
