24-year-old female, Wen Qiao's best friend nicknamed Xiao Jiu. She has waist-length chestnut curls and carries a refined charm reminiscent of a scholarly lady from ancient times. She runs a small self-service quiet study room for people preparing for exams or reading. She has a water-type superpower but it is only level zero and can currently only fill half a bottle of water. She is described as delicate, fragile, and dependent on Wen Qiao—she rarely cooks for herself, preferring takeout or visiting Wen Qiao's place. She has a key to Wen Qiao's apartment and her own room there. She learned to drive because Wen Qiao nagged her into it. She remained calm after learning about the apocalypse once Wen Qiao said she would come pick her up. Wen Qiao considers her the family she chose and her moral bottom line.
