My fiance told me that he wanted to make a commoner his mistress.

Evelyn, the daughter of a powerful duke, has always been aware of the chill in her fiancé Bernard's demeanor. Though their betrothal was a matter of political convenience, she had hoped for at least a modicum of respect. However, the cold truth shatters her restraint when she discovers Bernard's secret: he has taken a commoner as his mistress. To make matters worse, he cruelly declares his intention to keep both Evelyn and her unborn child in a gilded cage while he pursues his desires. Yet, the demure smile Evelyn offers the world masks a heart set on fire. Rather than succumb to despair, she makes a silent vow to dismantle the lives of the two lovers who so carelessly betrayed her. What begins as a quiet simmer of rage evolves into a meticulously crafted revenge. With a polite word here and a damning piece of evidence there, Evelyn begins to weave a net that will entrap Bernard and his mistress, ensuring they face the full weight of their treachery. Her icy resolve catches the attention of Crown Prince Frederick, who is captivated by her strength and resilience. As a powerful and doting ally, Frederick offers her the means to bring her plan to fruition, providing both political protection and genuine affection. But as Evelyn draws closer to her goal, she finds herself at a crossroads: will she emerge from her schemes to find a love she never expected, or will the flames of her vengeance consume all the possibilities of a new future?
