In the July 13 airing of KBS' 'Super Junior's Kiss the Radio', the Girls' Generation members talked about YoonA and her teasing.

YoonA explained, "That's how I show my love. I do that to make you guys laugh."

Sooyoung admitted that it is part of YoonA's charm, saying, "It's cute."

With her face turning red from laughing while she explained how she showed her affection, YoonA added, "Oh what should I do? My face keeps turning red," making the members laugh.
