Step by Step Seduction

Three years ago, Yun Yu and Qiao Xin had an accidental one-night stand. At the same time, Qiao Xin's younger brother, Qiao Zhan, was involved in a car accident and urgently needed a large sum for medical expenses. To raise the funds, Qiao Xin's father sold Qiao Xin to Lin Jiang, the driver who hit Qiao Zhan. Just at the critical moment, Yun Yu appeared and saved Qiao Xin. He promised to marry her but set three conditions; if she violated any, she would have to pay a billion-dollar penalty.
