Sweet and Well-Behaved After Transmigrating into a Book as Cannon Fodder

Chu Tong transmigrates into a book as a truly obscure supporting female character. The wealthy family's cannon-fodder daughter dies young because of her poor health, and her family is doomed after crossing the story's major villain, Su Yuqi. When they first meet, the major villain is still a pitiful boy everyone picks on. But Chu Tong knows that one day, he will become a business and medical powerhouse, able to turn the tide with a wave of his hand. The world both wants him dead and fears him. But Chu Tong knows that the boy is gentle and sweet. He'll bring her little biscuits, and he'll pay for her when she forgets her phone... And she will feel for him, trust him, and use what she knows about the plot to help the major villain avoid disaster and bring him warmth. At first, Su Yuqi wants to see what An Chutong is up to. But later, when An Chutong leaves, the well-behaved boy, Su Yuqi, grips the notebook, his gaze restrained and obsessive. “Liar. You promised you’d stay by my side forever!” He knows he’ll probably never become the person she hoped he would be. Then she appears again, and light returns to his world.
