Place it right after the unbelievable line in an edit, then follow it with Ceeday Huh for a second reaction and close with Oh My God Wow to finish the exchange.
이 사운드에 대해
This is a short vocal reaction built around a single stretched word, hein, delivered in one drawn-out burst lasting just over two seconds. It lands as a playful mix of confusion and disbelief, the kind of sound that makes a strange statement feel even stranger without saying anything more. It works best as a quick response, not a line of dialogue.
