★ The story focuses on hot social topics such as family of origin, adolescent development, school education, and social relationships, delving into the psychology of its characters. The protagonist, Chen Siqi, is burdened with real‑life struggles, and in her own way, she tears off the masks of everyone around her.

Chen Siqi, a 20‑year‑old female university student, rose to fame in her teens by publishing the girl‑and‑cat comic "Xiaojia and Me".At a book signing event, she was confronted by a female journalist, Xue Bing, who asked whether Siqi had "run out of talent". She was also accused by a hater, Tian Jingjing, of having abused and killed a cat. Two days later, after being harshly criticized by her professor, Bai Jingyu, in class for altering a tracing assignment, Siqi suddenly vanished.

Her mother (and manager), Jiang Hua, and father, Chen Wenbin, filed a police report, and criminal detective Qin Shuo took charge of the investigation. Two weeks later, Siqi's body was found. Seeking to hype the news, Xue Bing teamed up with Qin Shuo to investigate. They discovered that people around Siqi — her boyfriend Lin Yu, her pursuer Ma Mingyang, her hater, her parents, her teachers, and others — all seemed to have motives. Meanwhile, private investigator Yan Zhenshan's account, along with clues from Siqi's paintings and coded letters, indicated that Siqi had not only foreseen her own death but also gradually revealed an extremely tragic and darkly brief life.

From her disappearance to the discovery of the body and the decoding of the puzzles, from identifying suspects to analyzing motives and then eliminating them, each storyline and each character's past is laid out. The motives are so real they send chills down the spine. Every character exposes another side of human evil as the truth unfolds — a true "all‑villains" cast.
