Xia Yiran’s best friend from the art department of a neighboring university. Zhou Wanyue has shoulder‑length wavy hair and big eyes, giving her a naturally alluring aura. She is wealthy and often joins the group. She is supportive of Xia Yiran but also hides her own emotional trauma. She hires Su Wang to simulate the voice of her deceased friend (possibly a boyfriend) to comfort her at night. She suffers from guilt and self‑blame, expressing feelings that people have told her to die. She forms a secret arrangement with Su Wang, sending him voice messages and paying him. She is emotionally fragile and uses Su Wang’s skill to cope with loneliness.
