In the video, a person is seen pouring milk into a cup of coffee. The milk is poured in a circular motion, creating a swirl pattern on the surface of the coffee. As the milk is poured, it forms a heart shape in the center of the swirl. The person continues to pour the milk, creating a layered effect and enhancing the heart shape. The video ends with the finished latte art, a heart-shaped design on the surface of the coffee.
