A young woman with brown hair stands with her arms crossed against a black background with white Japanese characters, then the scene cuts to a blurry white and brown image, followed by a silhouette of a person in a kimono watching fireworks from a window, then a close-up of a person's legs and feet on a narrow surface at night with city lights in the background, then a young man and woman standing together in a field of white flowers under a blue sky with rain, and finally a silhouette of a person with their arm raised against a bright white background.
