On the December 15 broadcast of MBC radio PROGRAM, 'Sunny's FM DATE,' Sunny talked about age, revealing a time she wished she could stop aging.

She said, "When I was 22, I wished that I could stop aging.  This is because I was an idol and younger, prettier juniors were coming out.  Of course, I'm not saying that 22 is not a young, youthful, and pretty age.  At the time, I was sufficiently young and youthful.  My seniors were probably the same.  However, right at that age, I came to think that I wanted to stop aging.

Four years have already passed since then.  During those four years, there was just one thing I felt, and that was that it was kind of nice to naturally grow older and to gain more experiences.  I came to look forward to becoming thirty.  Of course I am looking forward to my thirties, but I'm not sure all of you are looking forward to my thirties. Can you guys imagine a 30-year-old Sunny?  I can't imagine what kind of Sunny I'd be.

It will probably be just as everybody imagines.  I think I would be a Sunny that is as immature as ever and will need to be taken care of by everybody else."
