Mood: The mood of the video appears to be romantic and nostalgic, with a sense of longing. The theme seems to revolve around love and relationships, possibly a rendition or a tribute to a classic love song. The use of 'Pehla Pyaar' (First Love) and the Deep House Mix suggests a blend of old and new, traditional and modern.

Environment: The setting seems to be an abstract representation of memories or a cityscape, with a background that resembles a collage of photographs or a cloudy sky. The environment is not explicitly shown but seems to be urban or a representation of a romantic getaway.
