A Ran, also referred to as Bai Yueguang (White Moonlight), is Xie Jin's first love and the woman he truly desires. She is a young lady from a wealthy family. Xie Jin keeps detailed materials about her preferences, including the fact that she does not like the color white. A Ran is never physically present in this chapter but is the central figure around whom Xie Jin's actions revolve. Yu Huan serves as her body double because of her resemblance. Xie Jin claims his heart belongs to her, though the narrative suggests this may be more about his obsession than genuine love. The concept of Bai Yueguang represents an unattainable, idealized first love in Chinese romantic literature.
