A young man in a blue and yellow jacket stands against a blue background, then the scene cuts to a group of young men dancing in a purple-lit room, with one in a pink and yellow jacket making a dramatic gesture, followed by a close-up of a man with dark hair and red glasses, then the group dancing again with one man in a white shirt with a butterfly design making a hand gesture, and finally a young man in a green and orange jacket is shown against a green background, first looking down and then pointing forward.
