On the June 3 airing of MBC's 'Duet Song Festival,' Super Junior's Yesung embarked on an adventure to find his duet partner, someone who's not already a singer.

When he was touched by challenger Cho Eun Soo's voice, he asked, "Who do you like the most among Super Junior members?" and Cho Eun Soo replied shyly, "Siwon."

This caused Yesung to reply with a light diss at his general fans.  He said, "You like the greasy type?" causing laughter.

To each her own!
