Deja Vu is the title track from Tomorrow X Together's 2024 EP minisode 3: Tomorrow, performed by the South Korean group TXT. The song's dreamy, nostalgic concept made its opening especially popular for short-form edits, where fans isolate the intro to signal romance, longing or a flashback. As TXT's fanbase continued sharing edits on TikTok, YouTube and soundboards, the brief intro became a recognisable shorthand for the track itself. It remains in use because it is instantly identifiable, emotionally clear and short enough to fit transitions, intros and mood-setting moments.

The opening intro to Deja Vu by TXT (Tomorrow X Together), a short atmospheric K-pop excerpt fans use for edits, intros and mood-setting fan videos.
The clip captures the first seconds of TXT's Deja Vu, opening with a soft, dreamy instrumental that builds gently before the melody takes hold. Its airy synths and slow, pulsing rhythm create a wistful, almost nostalgic feeling, like a memory resurfacing. Because it is only about eleven seconds long, it works as a quick emotional cue rather than a full song, instantly setting a romantic or reflective tone. Listeners familiar with Tomorrow X Together will recognise the track immediately, while new listeners still feel its calm, cinematic pull.
