Sherry is an exceptionally talented gatherer who has spent years collecting rare magical stones and medicinal herbs to support her younger sister Irene, the revered saint of the kingdom. Irene requires these special materials to activate her powers, and Sherry has risked her life in dangerous mountains and harsh weather to provide them, believing she is helping her only remaining family. But after Irene comes of age and becomes engaged to the second prince, she coldly tells Sherry she hates her and orders her to vanish from sight. Heartbroken and realizing she is no longer needed, Sherry decides to leave her home country behind and set out for the neighboring Rogue Kingdom, a land where magic flourishes and her skills as a gatherer might find a new purpose.

During her journey through a mountain storm, Sherry takes shelter in a cave and encounters Aslan, a strikingly handsome mage with black hair and crimson eyes. He is the head of the magic tower in Rogue Kingdom and is immediately impressed by Sherry’s knowledge and the pristine condition of the herbs she carries. Recognizing her as a prodigious gatherer, he offers her a position as his personal collector at three times the pay she previously earned. Though cautious at first, Sherry accepts a trial arrangement and begins a new life in Rogue Kingdom, where she is treated with respect and care for the first time. Aslan dotes on her, providing comfortable lodgings and warm meals, and Sherry slowly allows herself to believe she might deserve happiness.

As Sherry settles into her role, her relationship with Aslan deepens into romance. The two grow closer as they work together, and Sherry discovers what it means to be valued for her talents rather than exploited. The story’s central conflict resurfaces when Irene reappears, having let herself go after losing her fiancé’s favor and blaming Sherry for her misfortunes. During a festival ball in Rogue Kingdom, Irene confronts Sherry with resentment and demands she return, forcing Sherry to stand her ground and affirm her choice to leave behind those who only used her. The narrative follows Sherry’s journey from self-sacrificing servitude to self-worth, her blossoming love with Aslan, and her determination to never again be treated as an accessory to someone else’s glory.
