On September 22, Girls' Generation's management agency SM Entertainment shared a video of Yoona on YouTube.

While unboxing the merchandise, Yoona came across her photo card.
After taking a brief look at it, Yoona held it up high and said, "Wow... She looks amazing..."
She went on, "I mean, who is this, seriously?!", then she looked at the photo card again.

Following that, Yoona laughed out loud and apologized, "I'm so sorry!"
Then, she hilariously moved on to continue unboxing the merchandise as if nothing had happened.
