"Boynextdoor" returns with their fifth mini-album The Action, led by the single "Hollywood Action", a cheerful, retro pop song with strong swing rhythms and jazz elements. Catchy brass lines and energetic delivery create a lively, witty atmosphere that perfectly matches the group's personality. In the video, the members crash the set of a mock Hollywood spy-sci-fi film, perform choreography amid the production, and end up at a glamorous award ceremony, mixing parody with charm. The song immediately won over fans and brought them another "Inkigayo" win, reaffirming "Boynextdoor" as one of K-pop's most fun and creative new acts.
