Singer Sung Shi Kyung self-composed and sang the OST "Your Every Moment" for SBS drama "You Who Came from the Stars."

The OST publisher stated on the 7th, "After the broadcast, we've received numerous inquiries for Sung Shi Kyung's OST 'Your Every Moment,' so we decided to officially release the song on the 12th."

The song is gaining much interest because Sung Shi Kyung himself composed the song.

Regarding this, Sung Shi Kyung said on the 7th through his radio program MBC FM4U "FM Music City Sung Shi Kyung," Since Do Min Joon is an alien, I included alien sounds in the song, and used lyrics used the words 'light years' (the distance unit in space)."

He also said, "Today's version was not the final product, but a simple rendition with a piano accompaniment. The full version will be released next week."

The song of interest was played in the February 6th broadcast of "You Who Came from the Stars," when Do Min Joon (played by Kim Soo Hyun) and Chun Songee (Jun Ji Hyun) had a kiss scene.
