Shuga-Hyung.

A man with reddish hair stands on a stage, looking off to the side, then the scene cuts to him sitting on a red couch adjusting his tie, followed by a man with blonde hair on a stage under bright lights, then the same man with blonde hair standing with two others on a stage, then a man with brown hair holding a pen and looking at someone off-camera, and finally the man with blonde hair standing with others on a stage with green lighting. The setting alternates between a performance stage with bright lights and a dark background, and an indoor setting with a red couch and a window with blinds.
