Put this clip right after the reveal that ruins the plan, preceded by the sudden suspense hit to build tension, then follow it with the sad violin for the mock-tragic aftermath in fan edits and reaction cuts.
このサウンドについて
A roughly 19-second voice clip of someone shouting 'Why Nanako?!' in raw, escalating desperation, stretching the question far beyond a normal reaction. It feels anguished and melodramatic at first, then absurdly funny because the grief is so oversized for a single name, making the outburst sound like pure theatrical heartbreak.
