Super Junior's Yesung tweeted on July 18th, "Wearing Y style glasses. It's been a while since Two Woon," along with the above photos of himself and Kangin.

"Two Woon" is a nickname for the duo, created by combining the second syllable of Kangin (Young Woon) and Yesung's (Jong Woon) real names.

Fans commented, "They are both good looking," and "Please come on variety shows together."

Super Junior is currently actively promoting their newest single, "Sexy, Free & Single".
