Place it at the peak of a crush reveal, after a short setup and before the reaction shot. Follow it with the romance sound effect for the next beat, or lead into it with Anime Wow when the attraction is sudden and over the top.

This is a clean Deltarune sound effect lasting about 17 seconds, centred on a soft swoon that feels light and dizzy. It gives a dreamy, lovestruck feeling, like a character going weak at the knees over someone charming. It comes from Deltarune, the role-playing game, and suits gentle romantic or flustered moments.
