Mood: The mood of the video appears to be romantic and nostalgic, with a hint of eeriness or fear, as suggested by the tagline 'Fear Strikes Again'. The theme seems to revolve around love and possibly supernatural elements.

Environment: The setting seems to be a blend of traditional Indian and possibly Victorian-era London, given the architectural hints and the title '1920 London'. The background suggests a mix of cultural and historical elements, with the couple dressed in attire that reflects Indian tradition.
