I’m JaeBum.

A man in a blue sleeveless shirt looks at the camera, then the scene cuts to a group of men in casual clothes in a room, followed by a man in a black jacket looking at the camera, then four men on a dark stage performing, then a man in a red jacket raising his arm, and finally a man in a black leather jacket bending over on a stage with red lighting. The setting changes from an indoor room to a concert stage.
