Girls' Generation (SNSD) Yoona's handwritten letter is becoming an issue.

Recently in an online community, a picture was posted under 'Yoona's friendly note.'

In the revealed picture are the vitamin and little letter that Yoona had given out to drama "Love Rain" staff members. The note contains the excitement and the nervousness of Yoona as SNSD's first concert is drawing near, and she did not forget to thank the staff members.

Internet users who saw this commented, "Her heart is so pretty too," "How is her handwriting as pretty as her face?," and "The staff members are so lucky."
