Wandering dogs

A young man with brown hair and a determined expression is shown in a close-up, then the scene cuts to a white screen, followed by the same man in a brown coat standing with his arms outstretched in a dark, outdoor setting, then a shot of him from behind holding a long, thin object, then a young man with silver hair looking down with a concerned expression, and finally a close-up of a man with dark hair and a bandaged arm, wearing a brown coat and a green pendant, touching his face with a calm expression. The setting shifts from a dark, outdoor environment to a brightly lit indoor space.
