Place it at the peak of a romantic reveal, after a flirty line and before the reaction shot, then follow it with a Romance Sound Effect to hold the mood or an Anime Wow to widen the surprise, keeping it as the centre of the sequence.
Sobre este sonido
This is a short swoon sound effect lasting about a second and a half, with a soft, fluttery, breathy tone that rises and falls like someone melting on the spot. It feels dreamy, light and a little dramatic, turning a sweet compliment, a crush moment or a romantic reveal into something playfully over the top.
