An SM Entertainment rep stated, "Taeyeon will perform a duet with Kim Bum Soo during his concert on November 23... They will sing 'Man and Woman' together."
Taeyeon shared a photo of the song's lyrics on Instagram, "Man and Woman. Words that flash before my eyes by chance like the stars in my heart. Heart at my fingertips. Not as many raindrops as the thousands of words I have to say. Showers twelve times as much as the things I grow curious about. Love. The most common words in the world, Love you, which is why those words are more difficult to say. If I say, come with me," along with the hashtags, "#Man and Woman #Kim Bum Soo concert."
The two talented singers previously collaborated for the song "Different" in 2011, and they've also sang "Man and Woman" while Taeyeon was a DJ on the radio show 'ChinChin'.
Kim Bum Soo kicked off his year-end concert at K-Art Hall, Olympic Park on the 20th, which will run until December 1.
