Jhooooope!!

A man in a white t-shirt stands with arms outstretched, mouth open in a wide yell, against a textured wall with blue lettering. The scene cuts to a blurry motion shot of a person in dark clothing, then to a man in a white shirt and black cap biting his fingers while looking down, with Korean text on screen. The sequence ends with two men in a hallway, one in a black long-sleeved shirt standing behind another in a white and black shirt, both making playful, exaggerated poses.
