Kim Bum Soo and Park Jung Hyun are preparing to release a duet track for early August. Kim Bum Soo posted via Twitter, "I've always dreamed of a duet with Jung Hyun nuna. With Hwang Project", and attached the above photos as 'proof shots'. The duet will be produced by Hwang Se Jun, Hwang Sung Jae, and Hwang Chan Hee, also known as 'Hwang Project'. All of the track's proceedings will be donated to charity to help people in need. In related news, Park Jung Hyun and Kim Bum Soo, as well as YB, may be exiting from MBC's "I Am a Singer" through the newly implemented graduation system, creating the possibility of the August 8th episode being their grand finale.
