The sound comes from Kita Bikin Romantis by Indonesian band Maliq and D'Essentials, a romantic pop track whose title means we make it romantic. On TikTok, Reels and Shorts, creators shortened the title to Kitabik for short edits, using the brief, repeatable hook as a shorthand for affectionate, light-hearted moments. Its spread in Indonesia reflects how a familiar chorus can travel beyond the full song, becoming a recognisable cue for couple content, celebrations and gentle humour that still feels current in short-form video.
