Boom

A young woman with brown hair and a white shirt shouts with an angry expression, her arm raised, in a close-up shot. The scene cuts to a classroom where two girls in school uniforms fight, one grabbing the other's hair, while two other girls watch from a table. The scene changes to a bedroom where a girl in a pink tracksuit stands on a bed, looking down at three other girls in blue tracksuits who are lying on the bed. The girl in pink remains standing as the others react with surprise and start to move, one raising her arm, while the girl in pink maintains her position.
