Colette is a dedicated accountant assigned to the commoner tax department in the royal capital. Her ordinary life takes an unexpected turn when her superior demotes her, reassigning her to serve as the personal accountant for Prince Radis—a royal figure widely rumored to harbor a deep disdain for humanity. Left with little choice, she reluctantly accepts the role on a strictly temporary basis, hoping to endure the assignment and quietly return to her former position. However, her plan for a peaceful tenure shatters when the prince greets her with a devilish smile and reveals a startling objective: he has been searching for a child who secretly infiltrated the castle ten years ago. Panic immediately sets in as Colette realizes that the mysterious intruder he seeks might be none other than herself. If her true identity is exposed, she is certain it will result in her execution. Desperate to survive, Colette resolves that her only option is to resign from her post as the prince's accountant before his investigation uncovers her hidden past. What was meant to be a short-term demotion quickly becomes a high-stakes race against time, forcing her to navigate the dangerous waters of royal service while frantically plotting her flawless escape.
