Place this clip right after the surprising reveal in your edit, then follow it with the Oh My God Wow sound for a bigger reaction, or lead into it with Sudden Suspense when you want the reveal itself to land harder.
このサウンドについて
This 1.3-second clip is Yash saying 'Ok, that's very interesting' in a calm, slightly amused voice, with the emphasis landing on the last word. It feels politely curious rather than excited, like a raised eyebrow in audio form, perfect for a moment that is odd, unexpected or quietly impressive without needing a big reaction.
