Place it as a beat between a setup line and the reaction that follows, then follow it with the Rizz Sound Effect Button when the moment turns flirty, or with the Anime Wow Sound Button when the reveal deserves a bigger reaction.
Über diesen Sound
This clip is a single low, drawn-out 'mmm' hum lasting under a second, voiced with a soft, knowing tone and no other words or music. It feels sly and teasing, like a raised eyebrow caught in sound, and it works as a quick nudge when something is clearly good, tempting or a little too obvious to say out loud.
