Mood: The mood of the video appears to be melancholic and introspective, with a sense of longing. The black and white color scheme and the expressions on the faces of the individuals suggest a somber and emotional tone. The theme seems to revolve around heartbreak, love, and possibly regret.

Environment: The setting of the video seems to be a mix of indoor and outdoor locations, possibly a cityscape or a rustic backdrop, but the exact setting is difficult to determine due to the black and white color scheme and the collage-style image. The focus is on the emotions and relationships between the individuals rather than the physical environment.
