Place it right after a shot of an unanswered message, with the WhatsApp message sound just before it to set up the ignored text. Let the René line carry the reaction on its own, then follow it with the Kiko laugh to turn the callout into a group joke.
About this sound
This is a roughly ten-second Spanish voice clip built around the line “se hace el interesante, René,” delivered in a teasing, slightly exasperated voice. It feels playful and gossipy, like a friend pointing out that someone is pretending not to care. It works as light mockery for aloof behaviour, turning an obvious act into a shared joke rather than a real confrontation.
