Xu Xingyan and Lu Yongming, who have known each other since childhood, formed a symbiotic relationship due to a murder case - she climbed up the ladder step by step in the light like a shrimp, transforming from a poor girl to a wealthy heroine; he guarded and cleared obstacles in the dark like a goby, turning from a lonely boy into a sinful ghost. For eighteen years, they seemed to walk side by side in the white night, paving the way to the top with carefully planned conspiracies and cold calculations, until Lu Yongming ended everything with a decisive fall, and Xu Xingyan finally walked alone in a desolate world that has never lost the sun. This twisted bond witnesses the decline of human nature and reveals the unbridgeable rift between light and darkness.
