Fina, the Marquess's daughter, possessed only the modest skill of "hearing the voice of the earth," yet she was raised strictly to marry Banage, the heir to the prestigious House Dynar.

One day, her younger sister, Reina, was recognized for possessing the rare plant cultivation skill "Green Hand." As the Green Hand promotes crop growth and brings bountiful harvests, it is a highly prized skill, and Reina quickly became the center of adulation among those around her.

Because Reina had hated Fina since childhood, having always been compared to her talented older sister, she plotted to steal Fina's fiancé. Banage played along with her scheme.

As a result, at a ball she attended, Fina was locked in a lounge with a stranger—Hawk—and after being accused of infidelity, her engagement was annulled.

And her sister was to take her place as Banage's fiancée.

However, this was all orchestrated by Fina, who had foreseen Reina and Banage's plan.

Meanwhile, Hawk, the Margrave who learned of Fina's annulled engagement, felt responsible and proposed marriage to her.

Her new husband's family, House Rosayder, was simply poor and lacked any industry. Fina, by listening to the voice of the earth, discovered mineral veins, and the Rosayder Margraviate rapidly became prosperous.

Meanwhile, the production of gold ore, which should have been abundant for House Dynar, began to decline sharply. They came to realize Fina's true power, but by then, it was too little, too late.
