Use it as the payoff after the reveal in a short edit, following Sudden Suspense for the build-up and letting Oh My God Wow answer it a beat later for a bigger reaction.
关于此声音
This is a short, roughly 3.4-second vocal reaction built around a single drawn-out 'omg,' stretched out as if the speaker cannot quite believe what they have just seen. It feels shocked, giddy and a little overwhelmed, the kind of sound that lands when a reveal is too much to answer with a normal sentence.
