The first public broadcast of MBC's radio show 'Sunny's FM Date' took place at the MBC Golden Mouth Hall on November 14 with a guest appearance by duo group Casker.

While talking to Casker, they discussed the topic of being nineteen years old.  Sunny said, "It has already been seven years since I was nineteen.  That was when I debuted."

Casker's Lee Juno asked, "Your nineteenth year was different from others', so how was it?"  She replied, "At the time, I was barely able to go to school and practically lived in the training room.  After debuting, the rest [of my nineteenth year] went by in a hectic way.  If you look at it one way, instead of getting to enjoy my nineteenth year like how others could enjoy it, I had a nineteenth year that others could not have had.  I try to view it in the most special and positive way possible.  Still, I do feel a bit of envy towards people who enjoy a normal nineteenth year.  

However, if I tell them I feel envious like this, they tell me, 'But you're in Girls' Generation,' so I can't say it anywhere.  To me, the nineteenth year was a bit bitter.  If I were to go back to being nineteen years old, I think I would enjoy it a bit more freely than I had.  Once you become twenty, you get more responsibilities.  I wish everyone would enjoy a lot of things before you receive a lot of responsibilities."
