Place this clip right after the reveal as the first reaction, then follow it with Emotional Damage Meme Sound to stretch the embarrassment, or open with Bruh Sound Effect before it for a slower build to the same twist.
About this sound
This clip holds one short, strained grunt from Yajuu Senpai, rising like a laugh caught in a gasp and gone in just over a second. It feels sudden, silly and surprising, turning a quiet beat into an over-the-top reaction. The sound comes from the Japanese internet meme built around the character, where short clips were remixed and reused as reaction material.
