Li Yang, abandoned by her parents, and Mu Tinghe, fallen on hard times after his family’s fortunes took a turn, were rescued by police officer Li Chaoming. When they meet again years later, Li Yang doesn’t remember Mu Tinghe. But seeing her again, Mu Tinghe is drawn to her bright, resilient nature and falls in love with her. For years afterward, he watches over her in silence. Having grown up in a complicated environment, Mu Tinghe is young but cold and brooding, making people afraid to approach him, including Li Yang. Li Yang’s closest friend, Qiang Cheng, is an upright, kindhearted man with a strong sense of justice who achieves his dream of becoming a police officer. The demands of his profession and Li Yang’s tragic past become an impassable gulf between them. To Qiang Cheng, this is a source of regret. But even more painful is becoming a police officer and watching Li Yang die right before his eyes while saving his life.
