Cynthia lived a full life as a prominent merchant in the kingdom. When she awoke, she found herself reincarnated as her granddaughter, Clarice, who was facing unfortunate circumstances.

Clarice had an fiancé named Leopold. As the legitimate heir to an impoverished ducal family, he became engaged to her solely to use her as a financial resource, demanding in turn that she accept his infidelity, declaring, "I have no intention of loving you."

However, the reincarnated Cynthia adamantly rejects his demand. She informs him that any infidelity would lead to his ruin and, in turn, demands that he make an effort to maintain their engagement.

From then on, Clarice, once known for her meekness, undergoes a remarkable transformation, causing a stir among those around her even as she compels them to acknowledge her true capabilities.

Prince Allen, with his golden hair and blue eyes, takes an interest in her. He had been enamored with Cynthia in her previous life, and now, calling it a "second love," he falls deeply for her in her current incarnation, doting on her completely.

This is the story of an unfortunate viscountess who, empowered by her reincarnated grandmother, orchestrates a dramatic turnaround and finds her happy ending, doted upon by a prince.
