Mood: The mood of the video appears to be romantic and emotional, with a hint of longing. The title 'Kolkata Qutub Minar' suggests a connection to a place, possibly a monument or a landmark, which could be a central theme in the video. The overall theme seems to be a musical or a romantic ballad.

Environment: The environment appears to be indoors, possibly a room with wooden doors or panels, given the brown color and texture visible in the background. The presence of 'Kolkata Qutub Minar' in the title suggests that the video may also feature outdoor locations, possibly in Kolkata, and the Qutub Minar monument.
