Yoona will come and guest on Sunny's radio on its 100th day special.
She will appear in the 3rd and 4th segments on MBC radio's 'Sunny's FM Date' on the upcoming August 19th. The segments will have Sunny celebrating the 100th day of her radio and directly granting the wishes from the listeners. Yoona will appear as the one to deliver the wishes.
The radio staff said,"Since they're close to each other so we are highly anticipating to see how Yoona will ask Sunny for her wish during the live broadcast'.
The radio is currently collecting the listeners' wishes through its official website. In particular, Sunny is said to be preparing for her live singing on the radio for the first time ever since she became a DJ.
