A group of approximately ten to twelve female cheerleaders performs a routine in an indoor corridor or hallway. They are uniformly dressed in navy long-sleeved tops, some bearing the visible text "NBU," navy skirts with white trim, and white sneakers, each holding white pom-poms. The cheerleaders execute synchronized movements, including turning, stepping, and swinging their pom-poms. A dense smoke or haze effect permeates the background, creating a dramatic atmosphere for their performance. In the background, a large sign displaying the number '1' is visible, alongside what appears to be a flag, possibly the Bulgarian flag, faintly seen through the smoke. On the left side of the frame, an individual in grey sweatpants and a black t-shirt observes the cheerleaders, smiling. The setting is brightly illuminated by artificial lighting, and the floor is tiled. Given the "NBU" on the uniforms and the provided location context, the event is likely taking place at the New Bulgarian University in Sofia, Bulgaria. The cheerleaders appear energetic and focused, engaged in their performance or rehearsal.
