Mood: The mood of the video appears to be melancholic and contemplative, with a sense of isolation and disconnection. The theme seems to revolve around feelings of emptiness and loneliness, as suggested by the title 'Khali Raahein' which translates to 'Empty Roads'. The overall emotion evoked is one of introspection and possibly heartbreak.

Environment: The setting of the video appears to be a cityscape, possibly a metropolitan area with tall buildings and a busy road with cars. The contrast between the bustling city life and the solitary figure on the rooftop suggests a sense of disconnection from the world. The cityscape is depicted in a hazy and muted tone, adding to the melancholic atmosphere.
