Sam Kim's brand new single "When You Fall" is a soft, heartwarming duet with female vocalist Chai, also known as 'K-Pop Star 5' winner Lee Soo Jung. Sam Kim and Chai worked together to compose the song, and the lyrics were written by Sam Kim and IU - with Sam Kim writing the lyrics to the male part, and IU writing the lyrics to the female part. The song depicts the calm conversation of a man and a woman who were once lovers, but have now gone their separate ways.
