What is girl v line?

As an AI language model, I don't have access to all personal information of individuals. However, V line or V-shape face is a desirable facial feature in many Asian countries, especially South Korea. It refers to a face shape that is narrow at the jaw and wider at the forehead, creating a V-shaped jawline. Many girls in Asia consider it as a desirable feature and may do facial exercises, dieting, and cosmetic treatments to achieve it. It is important to note that beauty comes in all shapes and sizes, and everyone has their unique features that make them beautiful.
