Twenty-seven-year-old Su Man's life is like a glass of lukewarm water - a stable job, a small house with a mortgage, and a sweet but increasingly tired sibling relationship. Her lover Lin Yu, who is three years younger than her, has youthful enthusiasm, but also brings her unpredictable alienation and almost paranoid protectiveness. During a fierce argument, the nine-bead bracelet that carried Su Man's longing for her grandmother accidentally broke and the beads flew everywhere. That night, a dream that subverted her cognition tore apart her sleep: under the blood moon, a wingsuit girl (Fei Yuan) with a Barbie face but a top-notch athlete's body issued a stern warning, pointing the finger directly at Lin Yu, accusing him of "tearing apart the rules," "awakening the sleeping mark," and "attracting the attention of the scavenger." The world turned upside down in her dream, and Su Man was drawn into a bizarre secret realm, feeling a heart-piercing attachment that spanned time and space and many doubts about Lin Yu.

She collected the scattered beads and found that one of them was as warm as jade and slightly cool to the touch, as if it contained a secret.
Fei Yuan's warning is like a curse, constantly echoing in subsequent dreams or glimpses from high above the city: "The three-year period has not expired, and the price has not been paid.
