Place it at the reaction beat after a teasing line, then follow it with a tuturu for a second cute anime reply in the same scene. Keep it after the setup line and before any wider group reaction so the exchange stays focused on that one character.

This is a very short voice clip of a cute, high-pitched girl's voice repeating 'aña aña' twice in about a second. It feels sweet, shy and a little teasing, like a playful anime-style pout turned into a sound. The clip spread on TikTok under the Aña Aña name, where creators use that soft chant as a cute reaction.
