If you remember earlier this month, former Noel member Kang Kyung Sung had been enlisted into the army on 9th April. Before his enlistment, he had recorded a digital single with Kara's Nicole called Happy And for his fans. A UCC video of Kara (minus Seung Yeon) singing the song was uploaded recently onto the internet. It begun with Nicole and Gu Hara sitting in front of a notebook watching the MV probably, before Park Gyuri and then Ji Young joined them as they performed the song in a playful manner, with their cute, bubbly expressions and the odd laughter. Netizens commented, "Kara looked very cute and lively performing the song", "If only we could see Kang Kyung Sung and Nicole performing this on stage". credit: dream0hw The original Kang Kyung Sung and Nicole duet. credit: BbaBbaDyaYa
