A ballerina collaborated with a street dance crew for a performance. The street dance crew took the stage first, constantly changing formations and movements in sync with the music. The ballerina waited at the back of the stage for her entrance. As the music gradually slowed down, she began to join the performance. When the performance reached its climax, only the ballerina performed at the center of the stage while all the street dance crew members paused at the back of the stage. At the end of the show, the ballerina fully exited, and the street dance crew finished the performance at the very front of the stage in an unchanged formation.
