Mood: The mood of the video appears to be melancholic and introspective, with a sense of longing. The theme seems to revolve around heartbreak, love, and possibly regret. The use of black and white images in the background, with the central figure in color, suggests a focus on the protagonist's emotional state.

Environment: The environment seems to be a mix of urban and possibly rural settings, given the variety of backgrounds in the collage, including what appears to be a road or a village path. The overall setting seems to be India, given the language and the reference to a popular Bollywood movie 'Kabir Singh'.
