Create a 30-second, 1080p ultra-realistic outbreak-horror sequence taking place entirely inside a modern Korean corporate office, using the uploaded image as the highest-priority reference for the female lead and preserving her exact face, hairstyle, skin tone, body proportions and outfit. The young Korean woman works alone at her desk late at night when a strange coworker suddenly appears between the cubicles, breathing heavily and moving unnaturally. He collapses beside a workstation, convulses violently, then suddenly rises with bloodshot eyes and charges at another employee. The office erupts into panic as employees sprint between desks, knocking over chairs, monitors and papers. The woman runs toward the main entrance but sees infected coworkers flooding the hallway, forcing her to turn back. She and several survivors push desks, chairs and filing cabinets against the glass entrance doors as infected employees violently pound against them. Cracks spread across the glass before one panel suddenly shatters and infected hands reach through the opening. The survivors retreat deeper into the office and rush into a glass conference room, slamming the door behind them. They drag a large conference table against the entrance while the infected swarm surrounds the room. The woman notices a trapped coworker outside, briefly opens the door, pulls him inside and immediately barricades it again. Everyone falls silent, breathing heavily as infected silhouettes pound against the cracked glass. The office lights suddenly shut off, leaving only red emergency lighting as the glass begins to fracture under the pressure. End with the woman staring toward the camera in terror as the infected silhouettes completely surround the conference room, then cut to black; photorealistic Korean office environment, realistic physics, handheld camera, flickering fluorescent lights, atmospheric dust, natural office ambience, alarms, footsteps, screams, heavy breathing and pounding glass, no background music, no excessive gore, no CGI appearance, no distorted faces, no duplicated characters, no teleportation, no outfit changes, no subtitles, captions, logos or watermark.
