Mood: The mood of the video appears to be melancholic and introspective, with a theme of regret and apology. The title 'Sorry Song' and the expression on the faces of the two individuals suggest a sense of longing and remorse.

Environment: The environment appears to be an urban setting with a blurred background, possibly a city street or a public place. The focus is on the two individuals, and the background is not clearly defined, but it seems to be a modern and possibly trendy location.
