Transmigrated into an 1980S Novel, I Cling to My Childhood Sweetheart and Won't Let Go

When Su Ying wakes up, she discovers that she has been living inside a book all along. She is the original story’s hopelessly lovestruck supporting character. To follow and please the male lead, she gives him the job her parents left her, and he passes it on to his younger sister. She sabotages the marriage of the older brother who has always doted on her, causing his fiancée to marry an abusive man and spend her life unable to have children. Her brother turns against her, and they never speak again. To bring her second brother back to the city, she sells his return permit to someone else. He had gone to the countryside in her place because he feared she would suffer there, but she finds him a country woman who gets pregnant with his child and binds him to the countryside for life. Her brother is tormented to death by the woman and her family. On top of all that, the male lead’s family drains her dry, and she sells the house her parents left her to pay for his college education. She works back in their hometown to support him and his family, while he uses her money to buy a house in the city where he goes to college, marries the heroine, and raises a child in a happy, comfortable life. Once she has nothing left to offer, the male lead’s family sells her to human traffickers, and she meets a tragic end. After being reborn, Su Ying decides to stay away from the male lead’s family of leeches and treat her loving parents and brothers well. But… why was she reborn at the wrong time, right on the night she slept with the wrong person? And of all people, it was her childhood rival! Su Ying decides not to worry about it. He was the top scorer in the provincial exams and will be a big shot in the future, so she might as well cling to him first…
