This sound is best known online as a short Korean reaction clip rather than as a clearly documented quote from a specific film or show. It circulates on meme pages, short-form videos and edited reaction posts where creators need a quick spoken cue for suspicion, confusion or surprise. Its appeal comes from the compact setup: one direct question that instantly suggests someone has arrived, interrupted, or been noticed. That simple structure keeps it useful across many meme formats and language contexts.
About this sound
A short Korean voice clip saying “Who is it?” used in memes, reaction edits and surprise reveals when someone appears off screen or at the door.
This clip is a brief Korean voice line that sounds like someone asking, “Who is it?” in a sharp, curious tone. At just over four seconds, it works well as a reaction sound for sudden entrances, unexpected messages or off-screen interruptions. The line has a slightly suspicious, questioning feel, which makes a scene instantly more dramatic or playful. Creators often use it to frame a reveal, build tension before a cut, or add a humorous language-switch moment that catches the viewer off guard.
