Guzi transmigrated into a novel only to find herself as the false heiress, not the true one. Her engagement to a divorced man with three children contrasts sharply with the true heiress's arrangement to a military officer's son. Rather than follow the original body's tragic spiral—suicide attempt, parental abandonment, and eventual destitution—Guzi embraces her destined marriage. The role she dreaded transforms into unexpected joy: motherhood without hardship, a nurturing family without conflict. The true heiress endures constant struggles against her husband's illegitimate child and endless family disputes, bitter consolation being that Guzi's situation remains far worse. She believes herself fortune's favorite until fate intervenes. One day, Guzi emerges from a luxury vehicle beside the city's richest magnate, one hand protecting her swollen belly. Her aggrieved expression belies genuine affection as she protests, "We agreed not to have children." The powerful man beside her responds with tender regret: "I apologize—my mistake." As the true heiress watches in stunned silence, the false heiress steps into a destiny no novel predicted: genuine love, unimaginable wealth, and a happiness that transcends every plot twist.
