Girls' Generation's Sunny kindly posted a picture proving that she had received and opened up the letters sent from her sweet fans.

She revealed this through her Instagram on November 15 and wrote, "I love you all."

In the picture, her fan-written letters were lovingly and neatly placed on the floor, showing that her thoughtful fans spent a lot of time writing very neatly so their words were legible to Sunny.  The stationary was also very pretty and some pictures of Sunny were even included in these letters.  

It appears that Sunny was so touched by these letters that she decided to take a picture and show her fans that she had received and read them all.
