Super Junior's Yesung unveiled the concept for his new song "Gray Paper" for the SBS drama 'Wind Blows in Winter' OST alongside Siwon.

Yesung shared a set of selcas on his Twitter and wrote, "'Gray Paper' concept Y & S ^^ 'Gray Paper' live will air on this week's 'Inkigayo' GoGo !!"

The photos show Yesung donning an all gray suit and hairstyle to match the dark, sorrowful emotions of the ballad song. "Gray Paper" is described as a pop ballad that portrays the sad love between Oh Soo (Jo In Sung) and Oh Young (Song Hye Gyo) with the help of Yesung's soft vocals and producer Kangta's emotion-packed lyrics. It also serves as one of the main theme songs of the drama and topped real-time search engines immediately upon its release.

Catch Yesung's live performance of "Gray Paper" on 'Inkigayo' on the 17th!
