Girls' Generation's leader Kim Taeyeon will sing for the SBS drama's OST.

On March 7th, SBS announced that the singer will lend her voice to the drama's original soundtrack.

She will sing “And One” that was composed by label mate Kangta, who also composed the song “Gray Paper” sang by Super Junior's Yesung for the drama as well.

The song will talk about the romantic feelings Oh Soo (Jo In Sung) has for his “sister” Oh Young (Song Hye Kyo), and their impossible love.

Kim Taeyeon has rightfully earned the title of “Queen of OSTs” for her powerful, and emotional voice. Songs like “Can You Hear Me” for the 2008 drama “Beethoven Virus,” “If” for the 2008 drama “Hong Gil Dong,” and “Missing you like crazy” for the 2012 drama “The King 2Hearts” became big hits.

Musical director from the drama said, “We think Taeyeon will contribute to “That Winter, The Wind Blows” big popularity, as she is loved by her OST songs.”

The song was partly payed in the last scene of the episode aired today, March 7th, and you can hear the song bellow.
