Place it near the end of a short anime edit, just after the flirtatious setup peaks, so it acts as the payoff. Follow it with Yamete Kudasai for a stronger follow-up reaction, or lead into it with Anime Ahh to build the teasing first.
À propos de ce son
This is a short anime voice clip, lasting about 1.6 seconds, in which a flustered female voice delivers the line in a high, embarrassed tone. It feels awkward, teasing and deliberately over-the-top, like a reaction to affection crossing into uncomfortable territory. The exaggerated embarrassment is what makes it land as a joke rather than a serious moment.
