Place it at the end of a short reaction beat, just after the line it answers, then follow it with Awkward Moment for a lingering pause or Anime Ahh when the scene turns into surprise. Keep it as the final word in the exchange, so the next clip starts a fresh moment rather than extending this one.
이 사운드에 대해
This is a very short, roughly 1.7-second vocal clip built around a single sharp hmph, delivered as a quick huff rather than a spoken word. It feels unimpressed and mildly annoyed, like a small scoff at something not worth answering. The sound lands as a light, playful dismissal, the kind of reaction that makes a reply feel complete without saying anything more.
