The image shows two young men standing in front of a blackboard in a classroom. The man on the left is wearing a white lab coat and glasses, and is holding a green marker in his hand. He appears to be explaining something to the other man, who is standing with his back to the camera. The blackboard behind them has various drawings and illustrations on it, including a heart, a flower, a butterfly, and a bird. The drawings are colorful and detailed, and there are also some letters and symbols scattered throughout the blackboard. The overall mood of the image is one of concentration and focus.
