Put this clip as the final reaction in a short edit, right after the reveal or result lands. Build into it with the naruto sad song during the setup, then switch to this sigh, and layer awkward crickets just before it if the pause needs weight.
关于此声音
An elongated, breathy sigh stretches for most of the clip, trailing off into a soft spoken 'Duggie' at the end. It lasts just a few seconds and stays quiet and flat throughout. The feeling is plain disappointment and tired resignation, the sound of someone deflated by bad news rather than angry or surprised by it.
