Place it just after the excuse or claim in your edit, then follow it with Oh My God Wow for a bigger reaction and finish with Damn to close the exchange, keeping the sequence short so each reaction gets its own beat.
このサウンドについて
Ainn is a short vocal reaction clip centred on one drawn-out, expressive utterance, running for about twelve seconds. It carries a playful, slightly exasperated edge that makes a listener smile at the over-the-top delivery. That light, teasing tone suits a moment of mock disbelief, turning a small reaction into a clear, memorable beat without needing any extra words.
