Mu Xuan is the original female lead of the novel, a beautiful and elegant woman who is the girlfriend of Wen Junmu, the second brother. In the original plot, she received the space jade bracelet from Wen Xin and used it to hoard supplies during the apocalypse, later partnering with the male lead Huo Shuyan and discarding Wen Junmu cruelly, leading to his death. In this timeline, she appears to be reborn or retains memories of the previous life, as she actively seeks the jade bracelet, demonstrating manipulative and selfish traits. She is initially gentle and composed but becomes anxious and relentless when her plans are thwarted. She lies to Wen Xin, claiming she heard about the bracelet from Wen Junmu, and tries to borrow it under the pretense of matching her dress. When Wen Xin refuses, she cannot hide her fury. She also pursues Wen Junmu only for his usefulness, showing no real love or loyalty. Her ambition is to secure the space and ensure her own survival, even if it means using others. Despite being the female lead, her actions in this story are antagonistic from Wen Xin's perspective, as she covets the space and embodies the threat of betrayal and exploitation.
