“3D” is an R&B pop song by South Korean singer Jung Kook. The track uses an impressive minimalist instrumental composition and percussive rhythms to create a nostalgic sound. The song is the second mainstream solo release from the singer after “Seven,” in July 2023.

On the song, Jung Kook expresses his strong feelings for someone he can’t reach with a witty touch. Since he can’t be there with his significant other, he chooses to watch in “3D.” The single features American rapper Jack Harlow, marking their first collaboration.

The song was released alongside its music video, which allowed Jung Kook to showcase the crisp choreography for the track.
