Assistant Yan is Tan Ci's loyal assistant, often accompanying him to meetings and handling his schedule. He is initially skeptical of Wu Yin's divination abilities, dismissing her as a fraud after she describes Tan Ci's background based on publicly available information. However, after the accident on Hongyang Road is avoided, he becomes a believer in her skills, expressing his awe and remorse for his earlier doubt. He is professional in his work, promptly canceling Tan Ci's appointments and adjusting their route after the warning. He is also curious about Wu Yin's origins, questioning her about her surname and background. He is observant, noting the resemblance between Wu Yin and Cheng Yining in the photos from Tan Ci's safe. He is somewhat impulsive in his reactions but ultimately respects Tan Ci's decisions and Wu Yin's abilities.
