TaeTiSeo's third supportive guest has arrived and she's none other than Yoona.
However, there's a catch and Yoona has become a cake delivery girl for the trio. In a short clip recorded by Tiffany on her instagram, Yoona is excitedly running down and knocked on TaeTiSeo's waiting room and handed over a cake.
Seems like Seohyun wanted to make it hilarious and turned down Yoona which makes her react cutely. How supportive of her.
Watch the clip below:
