A photo of Taeyeon grabbing Yoona’s collar has attracted attention from fans.
A forum uploaded a short video with the tittle ‘Scary leader Taeyeon grabs Yoona’s collar’. It was taken when SNSD made a surprise visit to SMTOWN Pop-up store to promote I Got A Boy.
They were surrounded by security guards when suddenly Taeyeon grabbed Yoona’s collar and ‘angrily’ shaking it. Then when Yoona started explaning something, Taeyeon put her hands down and showed a mischievous laughing expression.
