In the video, a person's hand is seen holding a green marker and writing on a piece of paper. The person is writing the letter "B" in a blue box on the paper. The background of the video is blurred, but it appears to be a room with a table and a lamp. The person's hand is steady as they write, and the marker leaves a bold, green line on the paper. The video is shot from a close-up angle, focusing on the person's hand and the paper.
