A photo titled “A scary leader Taeyeon grabs Yoona’s collar” was recently posted on the internet. This was taken when Girls’ Generation made a surprise visit to SMTOWN Pop-Up Store for their new album, I Got a Boy. Surrounded by security guards, Taeyeon shyly grabbed Yoona’s collar and started shaking it. However, as Yoona explained something, Taeyeon let her go free. Don’t you want to know what they were talking about?
