Concealed jealousy

The prompt

Close-up of a glamorous Korean actress in a sequined gown seated in an awards-show audience, polished broadcast-glamour look, steady camera. 0–2s: she watches the stage with a bright, expectant smile. 2–5s: the guests around her begin applauding someone else; she stretches her smile wider while her eyes tighten and stop smiling. 5–8s: the smile turns rigid, then slips slightly at the corners as she keeps clapping. Throughout: warm spotlight haze, a softly blurred audience in tuxedos behind her, sparkling camera flashes, the camera holding steady on her strained composure.
