Khả Nguyệt Lam, a dedicated automotive engineering student, spent her days beneath cars, meticulously maintaining them. One fateful day during her internship, a car lift collapsed, crushing her upper body. Believing her life had ended in a tragic industrial accident, she awoke to find herself in a bamboo forest, pursued by hyenas, only to be rescued by a mysterious stranger. It was then she realized the impossible: she had transmigrated into a novel. The book was 'Thiên Tử Nam Dương,' an ancient romance she had read in her first year of college. It featured a beloved, handsome emperor as the male lead and a framed minister's daughter as the crying, yet popular, female lead – a character Khả Nguyệt Lam never particularly liked. To her surprise, she wasn't the protagonist, an antagonist, or even a minor supporting character; she had become an entirely new entity within the story. But the biggest shock came when she found herself sharing a home, meals, and even a bed with the novel's most despised supporting male character, and had even borne him twins! She despised him, too! He was supposed to be a cunning, ruthless schemer vying for the throne, destined for a gruesome end. Yet, here he was, acting adorably spoiled and demanding her affection. What had gone so wrong?
