A modern woman transmigrates into a novel's ending as a street beggar. Desperate for food, she stops a pink carriage and catches the eye of a volatile prince. He abducts her because she resembles his sworn enemy, a former princess, and forces her to be a 'substitute foe' with an outrageously high salary. She endures his cruelty for the money but gradually discovers the broken past beneath his arrogance. As conspiracies unfold and her true lineage surfaces, he must confront whether he hates her face or has fallen for her vibrant soul.
