Mood: The mood of the video appears to be energetic and youthful, with a theme of nostalgia and reminiscence, as suggested by the title 'Hustle 2.0' and the song title 'Bachpan' which means 'childhood'. The overall emotion evoked is one of excitement and playfulness.

Environment: The setting of the video seems to be a television studio or a music show setup, with a bright and colorful background, and a TV screen visible behind the main performer. The presence of a microphone and a live audience or other performers in the background suggests a live performance or a recording of a music show.
