the best boy

A laptop displays a video-sharing website with three clips; the main clip shows a group of men in black clothing performing a synchronized dance routine on a city street, while the other two clips show different dance groups. The scene cuts to a close-up of two people, one with braided hair, smiling and looking at each other, then cuts to an anime scene where two characters are lying on their backs, looking up at each other with expressions of surprise and amusement, with the text "Uguu~ You copied me again!" appearing on screen.
