Guzi's transmigration into a novel landed her in an unexpected role—the fake heiress in a tale of two daughters. While other transmigrated souls claimed the true heiress position, Guzi found herself cast as the imposter, with a cruel twist: both were engaged. The true heiress secured a military commander's son, leaving Guzi contracted to a divorced tycoon with three children from his previous marriage. Her parents, favoring the genuine heiress, forced Guzi into the substitution. In the original story, this sacrifice drove her to a failed suicide attempt, loss of parental affection, and eventual ruin—mistreated stepchildren, a divorce, and death as a penniless beggar on the streets. But Guzi rewrote her fate. Accepting the marriage willingly, she discovered an unexpected truth: raising the tycoon's children and caring for his elderly father brought genuine fulfillment rather than torment. The original Guzi had made a catastrophic error in judgment. Meanwhile, the true heiress battled her own nightmare—an illegitimate child, inheritance disputes, and relentless family conflict. She consoled herself knowing Guzi faced worse: a ready-made family and no glory. Then came the moment that shattered her certainty. Guzi emerged from a luxury vehicle, heavily pregnant, cradled by the wealthiest man in the city. "We agreed—no children," Guzi protested, her expression stricken. The man smiled apologetically. "I know. I'm sorry."
