Place it immediately after the question in your edit, so it acts as the answer and closes the moment. Follow it with a Yaaaay cheer when the yes needs a bigger reaction, or lead into it with a Bruh for a reluctant yes that still counts.
このサウンドについて
This is a short 1.2-second voice clip of a man saying 'Ja', the Dutch word for yes, in a clear, upbeat tone. It feels cheerful and instantly agreeable, like a quick nod you can hear, and it works as a light, positive reaction rather than a serious answer. The clip was made by Niels himself, which gives the single word a personal, homemade charm.
