The video shows a man and a woman in a classroom. The man is wearing a red shirt and is standing in front of a chalkboard, writing on it with chalk. The woman, who is wearing a pink shirt, is sitting on a chair and watching the man write. The man appears to be explaining a mathematical concept, as he writes out a series of equations and diagrams on the board. The woman seems to be listening attentively, nodding her head as the man speaks. The classroom is well-lit, and there are no other people visible in the video.
