Shen Aman transmigrates into the body of a maid in the Crown Prince's residence and is exiled to Ningzhou alongside Zhao Ye, the former Crown Prince who was falsely accused, stripped of his title, and left with both legs shattered. With Zhao Ye gravely wounded and on the brink of death, his will to survive at a mere 3%, Shen Aman unexpectedly becomes bound to a system tasked with saving the Crown Prince—if the male lead dies, she will be erased. Trapped in a dilapidated courtyard with only five kilograms of rice, Shen Aman relies on her strength to reclaim wasteland, gather medicinal herbs, and sell braised delicacies at a street stall. She grits her teeth through cleaning Zhao Ye's wounds, treating his injuries, finding doctors, and nursing him back to health, all while enduring harassment from local thugs and rejection from the neighbors. Gradually, the two move beyond their master-servant relationship, once defined by rank and status, to become each other's only support in desperate circumstances, turning the bitter days of exile into a life filled with warmth and vitality.
