Place it at the end of a helpful scene, just after the favour is shown, then follow it with a cheer sound to finish the scene with a clear thank-you payoff.
Sobre este som
This is a short 1.5-second voice clip in which a speaker repeats merci merci in a warm, upbeat tone, turning a simple thank-you into a small performance. It feels playful and affectionate rather than formal, like gratitude delivered with a grin, and its quick, repeated phrasing makes it easy to recognise and fun to drop into a light moment.
