Tiffany reveals she's done romantic events close to handwritten letters before, possibly to Nichkhun?

On the June 17 installment of On Style's 'Jessica & Krystal,' Jessica hung out with fellow Girls' Generation members Hyoyeon and Tiffany as they flipped through a dating psychology test and divulged their dating styles.

Hyoyeon said, "What would be a good and touching present to give your significant other on a celebratory day? �Album production for just the two of you, a moving handwritten letter, a vacation for just the two of you or a special party."

Unsurprisingly, attention was focused on Tiffany (currently dating 2PM's Nichkhun), especially as she said, "There was a time I did something similar to the second one, [a handwritten letter]," surprising the other two. �As the atmosphere got strange, Tiffany yelled, unable to stifle her laughter, "You can do that because it's a commemorative day."

Hyoyeon said, "At this age, it's a problem if you didn't get to date even once." �Tiffany said, "I don't think I should talk."

Do you think the event that Tiffany mentioned was for Nichkhun?
