Mood: The mood of the video appears to be serious and intense, with a hint of action and drama. The theme seems to revolve around a story of love and relationships, as indicated by the title 'Prem Ki Duniya' which translates to 'World of Love'. The overall emotion conveyed is one of anticipation and intrigue.

Environment: The setting of the video appears to be an outdoor location, possibly a rural or semi-urban area, with a tiled roof and a wooden sign in the background. The presence of a sign with non-English text suggests that the story may be set in India or have Indian connections.
