The Korean phrase nunmuljuyi literally warns viewers that tears may follow, and that warning has become a familiar shorthand in short-form video culture. Creators label emotional edits this way to set expectations before a sad twist, a nostalgic flashback, or a heartfelt message, letting the audience prepare for an emotional payoff. Because the phrase is instantly recognisable to Korean-speaking viewers and easy to copy as a caption, it travels well across edits, reaction videos, and fan compilations, where it signals sentimentality rather than comedy or shock.
