Xu Zhining, an image comparison analyst from a wealthy family, discovers after giving birth that she can see precognitive bullet comments—scrolling on-screen messages that reveal what is about to happen. Through them, she sees through her best friend Shen Lu's scheme: whose beloved son is gravely ill, Shen Lu covets the trust fund of Zhining's family and teams up with Zhining's husband, He Yanxing, and the maternity nanny to swap the babies. Step by step, Zhining lays her traps and, at the trust ceremony, publicly exposes the pair's affair and their plot to steal the family fortune—forcing He Yanxing to walk away from the marriage with nothing. She also uncovers the secret that her mother-in-law, Wei Lan, had her biological child swapped years ago, and that He Yanxing is, in fact, an adopted son. She helps her mother-in-law reunite with her real son, Lu An. Driven into a corner, He Yanxing and Shen Lu strike back desperately, playing the victim and smearing Zhining's name—only to be utterly defeated and reap what they sow. In the end, Zhining breaks free from her past, gradually falls for Lu An, protects her son, and finally wins the stable life she deserves.
