Jung Yong Hwa’s recent backside captured images has been making BOICE went insane. The picture was from the making of CN Blue’s music video for its Japanese third single Come On. Wearing a sleeveless shirt, Jung Yong Hwa roamed around the practice studio, flexing his muscles and clearly showing his ‘butterfly’ muscles peeping out from his shirt. You can see his arm muscles on 3:32 mark and start drooling.
