Sophia Holt finds herself transmigrated into a novel, waking up not as a heroine, but as a destitute beggar. Her struggle for survival takes a dangerous turn when she is captured by the cold-blooded Prince Arthur, who mistakes her for his sworn enemy, Princess Eleanor. Forced into a high-stakes charade to act as the Princess's double, Sophia must navigate the treacherous court intrigues while enduring the Prince's initial cruelty. However, as they navigate daily life together, the dynamic shifts. Sophia discovers the trauma hidden behind Arthur's icy facade, and he finds himself drawn to the woman he is supposed to hate. When conspiracies unravel and Sophia's true identity—and origin—are exposed, Arthur faces an impossible choice: punish the face of his enemy, or embrace the soul that healed him.
