Lin Yu's college roommate and the primary antagonist. In the past life, she and Lin Yu were traveling in Yun Province when the apocalypse struck. Both awakened supernatural abilities, and Lin Yu joined Bai Yanyan's ability-user team. While traveling toward Dawn Base in Province A, City S, Bai Yanyan was caught stealing food supplies from the team. Fearing exposure, she framed Lin Yu and convinced the team to sacrifice her. She personally stabbed Lin Yu in the heart and kicked her off the vehicle into the zombie horde. She continues to call Lin Yu in the present timeline, pretending to be concerned about their planned trip to Yun Province, while secretly gloating about the suppressed Apocalypse Survival Guide article.
