All I know

A group of people walk through a crowded indoor space, moving forward in a line. A person with long brown hair is seen from behind, walking quickly. A train car with graffiti reading "COOLRISKY" passes on tracks. A person on a bicycle rides at night, with smoke or steam in the background. Three women jump into a swimming pool simultaneously. A woman in a light-colored hoodie and black pants performs a dance move on a brick surface.
