इस साउंड के बारे में
This is a very short Japanese voice line, lasting under a second, in which the speaker delivers the words 'nante koto wo' with rising anger. The clipped delivery makes the disbelief feel immediate and confrontational, like a scolding caught mid-sentence. It lands as a sharp burst of indignation, suited to moments of shock, betrayal or a decision that has gone badly wrong.
