Mood: The mood of the video appears to be melancholic and introspective, with a sense of longing. The title 'Kash Maar' which translates to 'if only' or 'wish', suggests a theme of regret, nostalgia or yearning. The somber expressions on the faces of the two individuals also add to the melancholic tone.

Environment: The video seems to be set in a mountainous region, possibly in the Himalayas, with a mix of bare and blooming trees, and a stone wall in the background. The scenery suggests a serene and natural environment, which contrasts with the somber mood of the individuals in the foreground.
