An innocent yet stubborn peace-making princess and a pitiful, strong, crazy hostage prince in a mutual salvation story; transaction first, falling in love later. Shen Mingshu has transmigrated into a book, becoming that cannon fodder princess from the original story who only had a single line of text: 'Three months after arriving at the royal court, she died of illness.' While others transmigrate and get the female lead script, her opening move is at hell difficulty. A drafty tent, a snowfield that freezes people to death, and a good-for-nothing system buzzing in her mind: approach the male lead, win him over, make him fall in love with you. Looking at the man tied to the execution stake before her, covered in blood, who had just used a shattered bone to pierce the eye of his abuser, Shen Mingshu fell silent for three seconds.
