While trying on her wedding dress, heiress Song Zhixia sees a vision of her future self in the mirror, warning her never to marry her fiancé, He Tinglan. The vision reveals Tinglan is having a secret affair with Zhixia's best friend, Ming Yi, and together they plan to poison her during pregnancy to steal her family's fortune. Finding a mysterious future miscarriage consent form, Zhixia investigates and discovers they have been lacing her daily vitamins with blood thinners. Confronting them before her family, Zhixia uncovers the physical evidence in Ming Yi's purse, cutting ties and reporting them to the police.
However, the future vision warns her again: Tinglan's father is scheming to declare Zhixia's father mentally unfit to seize her family's company. Zhixia thwarts the plot in the hospital with secret audio recordings. Digging deeper, Zhixia discovers Ming Yi also possesses a shattered mirror predicting the future, which she used to forge a luxury brand inheritance for fraud. Zhixia exposes the scam publicly, driving Ming Yi into total ruin.
The horrific ultimate truth emerges: Zhixia’s late mother didn’t die of an illness, but was murdered in a car crash engineered by Tinglan’s father to silence her over financial crimes—a crime Tinglan knew and hid for years. Cornered, Tinglan attempts to burn down the bridal shop with Zhixia inside, but police arrest him at the scene.
With all villains imprisoned, Zhixia reclaims her mother's bridal design brand. The magic mirror vanishes forever as Zhixia steps into a bright new life of self-love and independence.
