SM The Ballad's Jonghyun and Taeyeon kicked off the releases with their soothing Korean duet "Breath" yesterday, and today Jonghyun is back alongside Chen for the song "A Day Without You" (Korean title: "One Day")!

The new track sings of the emotions of a man who says he feels free after his break up, but is actually in pain emotionally. 

In addition to the new track, the Japanese and Chinese versions of the song "Breath" have also been released in their respective countries ahead of their reveal in Korea. Chen and Zhang Li Yin (aka Jang Ri In) sing the Chinese version of the song, while Changmin and Krystal lend their voices for the Japanese version.

So check out "A Day Without You" and the Chinese and Japanese versions of "Breath" below!
