Mood: The mood of the video seems to be nostalgic and melancholic, with a hint of bittersweetness. The theme appears to revolve around longing, separation, and possibly the journey of life. The use of a cassette tape and the title 'Side A Side B' suggests a storytelling approach that might explore different perspectives or sides of a story.

Environment: The setting of the video seems to be a mix of urban and possibly rural landscapes, given the presence of cityscapes, open roads, and natural scenery in the background collage. The overall aesthetic is warm and golden, suggesting a focus on personal, intimate moments and possibly a road trip or travel narrative.
