Place it at the peak of a reveal, after a short build-up, then follow it with an Anime Wow for the next beat and a Rizz sound for the crush payoff, keeping the swoon as the centre of the sequence.
Über diesen Sound
This is a just-under-five-second vocal swoon from a Deltarune Roaring Knight live-action roleplay, a rising breathy gasp that folds into a soft, defeated sigh with no music behind it. It feels funny and over-the-top, like someone losing all composure at once over a crush or a villain. It comes from fan-made roleplay around Deltarune, not the game's official soundtrack.
