"Peeping into Women's Hearts" tells the story of a photographer, Yang Ping, and the different emotional stories between him and five girls. It combines elements such as love, time travel, and martial arts. Yang Ping met a little girl in his childhood, but not long after, because the little girl's family moved abroad, Yang Ping never saw the little girl again. From then on, Yang Ping no longer photographed women, and every time he photographed the scenery, his personality became less approachable, and he was especially indifferent to women, until an accident at work, he rented a film camera in a mysterious camera shop, but gained the ability to peek into other people's worlds. Yang Ping traveled to the world of four women: a glamorous star, an upright lawyer, a hard-working bookstore manager, and a star assistant who lacked attention. He found that there was an unknown secret behind each woman. However, Yang Ping met Wu Meiwen by chance through a friend, a woman who could be said to be white, rich and beautiful. Due to business, Wu Meiwen was very secular on the surface, but Yang Ping never traveled to Wu Meiwen's world, but they had a good impression of each other, and finally coincidentally discovered that Wu Meiwen was the little girl of that year. After peeping at different women, Yang Ping felt tired of peeping and gradually got tired of this kind of life. When he wanted to return the camera, something even stranger happened. The owner said that the camera was his own, but the camera he had thrown into the sea. In the end, Yang Ping finally let go of his desires, did what he wanted to do, and loved who he wanted to love!
