Mood: The mood of the video appears to be romantic and melancholic, with a sense of longing. The presence of a couple in the background, silhouetted against a rainy backdrop, suggests a emotional and intimate atmosphere. The title 'Tum Bin' which translates to 'Without You', implies a theme of love, loss, and separation.

Environment: The setting of the video seems to be a rainy, urban or semi-urban area, possibly near a railway track, given the presence of train tracks in the background. The streetlights and trees in the background add to the ambiance of a city or town at night.
