Girl walks past train with skirt up

You’re at a subway station, maybe waiting for a train or just passing through. A girl walks by, maybe in a hurry, and her skirt rides up a bit as she moves. She’s not looking back, just focused on walking. People are sitting around on benches, some looking at her, some not. One guy in a white shirt is sitting with his legs out, maybe watching her go by. The train is blue and parked nearby, doors open, lights on inside. It’s not a big deal, just a normal moment that turns into something unexpected. The vibe is casual, like you’re just there, and then suddenly you’re noticing something you didn’t expect. No big drama, just real life happening in a public place.
