Mood: The mood of the video appears to be melancholic and introspective, with a sense of longing. The title 'Phir na milen kabhi' which translates to 'Never meet again' suggests a theme of heartbreak, separation, or lost love. The overall emotion conveyed is one of nostalgia and yearning.

Environment: The setting of the video seems to be a dimly lit, intimate space with soft lighting, possibly a room with candles lit in the background. The dark background and the soft focus on the candles create a warm and cozy atmosphere, which contrasts with the melancholic mood of the title.
