Place this clip right after the reveal in your edit, then follow it with a tuturu sound button for a lighter anime beat, or swap that second slot for an anime ahh sound button when the reaction needs to escalate instead of soften.
Informazioni su questo suono
A very short 0.6-second voice clip of someone blurting out 'Honto ni!?' in Japanese, the words for 'really!?' delivered as a quick, high, startled question. It gives a listener an instant feeling of disbelief and surprise, like hearing news so unexpected you need it repeated before it can sink in at all.
