A man in a black jacket with "PEE" and "35" logos sits on white stairs under pink lighting, gesturing with his hands. The scene cuts to a man and a woman dancing in silhouette against a pink wall, then to a man in a green sweater dancing in a blue-lit room, followed by a woman in a black tank top and cap dancing against a white background, and finally to the man and woman dancing in silhouette again.
