In appreciation for all the good wishes given to her on her special day by SONES the world over, Yoona did a thank you UFO.
Many, many SONES the world over have been giving their best wishes to Yoona on her recent birthday (30th May 2011).
In response, Yoona wrote a UFO to thank her fans for the good wishes and support. She promised to do her best and that she will be back soon. In true Yoona fashion, she wished for good health for everyone and encouraged all and sundry to enjoy the current good weather :D.
