Place this clip right after the reveal in your edit, following a confused pause. Pair it with the huh-ceeday reaction first for the misunderstanding, then let this play, and finish with oh my god wow for a bigger second reaction when the scene needs escalation.
このサウンドについて
This clip is a short vocal reaction lasting just under four seconds, built around a drawn-out 'ohh' delivered as a single expressive exclamation. It feels playful and theatrically surprised, like a pleased gasp that leans into the moment rather than a startled shout, which makes the reaction read as amused recognition instead of genuine shock or alarm for the listener.
