"River!!"

A young boy with glasses in a suit speaks while sitting at a piano, then appears in a white t-shirt crouching in a blue industrial area, followed by a scene of him in a yellow shirt at night looking at his wristwatch, then walking outdoors in a blue shirt, then in a bubble bath, and finally smiling in a park. The sequence shows a young man in various settings and situations, including indoor and outdoor environments, with a focus on his changing expressions and attire.
