Candid Charm: K-Pop Idol on Stage

Analog film photography aesthetic, heavy film grain, Kodak Portra 400.

A candid, natural portrait of a young Korean female K-pop idol sitting casually on the edge of a dimly lit wooden concert stage during a soundcheck. She has a "pure yet sexy" vibe, looking at the camera with a shy, gentle smile. Minimal, natural makeup, slightly messy hair.

She wears a simple white ribbed short-sleeve crop top and a vintage-style red and white striped A-line skirt (a subtle nod to the diner uniform colors). White sneakers.

The background shows microphones, cables on the floor, and empty auditorium seats blurred out. Soft, warm ambient stage lighting, authentic light leaks, nostalgic atmosphere. Not excessively flashy, no aggressive LEDs.
