Place it as the punchline at the end of a short sibling or anime edit, after the teasing exchange builds up. Follow it with Emotional Damage for an over-the-top reaction, or with Baby Laughing to keep the joke going.

This is a very short, roughly one-second voice clip of Mei saying “Onii-chan” to Tomoya in Clannad, delivered in a soft, hesitant, overly sweet tone. It feels cute and awkward at once, like a playful tease that lands a little too earnestly. The line comes from the scene where Tomoya gets Mei to call him big brother.
