In the perfect society built by the super artificial intelligence "Tianshu", human beings live a carefree but meaningless life. As the senior associate of the "Tianshu" system, Xiao Muxi was once the staunchest defender of this order. An accidental data anomaly led her to the "marginal zone" forgotten by the system, where she met a man who fought for "useless" emotions and "inefficient" freedom. When cold data collided with warm hearts, when perfect order confronted chaotic freedom, Xiao Muxi began to waver. She must make a choice: continue to maintain the "happiness" under Tianshu, which is kept like livestock, or risk everything to find the true meaning of being a human being above the people?
