Everyone in the Yu family thought that Yu Wan had escaped. However, Yu Wan had not actually left S City.
In her plan, there was no such option.
Ever since the DNA test, there had been no news from the Yu Family.
She thought that this meant that she and Yu Hong were indeed related by blood. On one hand, the Yu Family hated her as an illegitimate daughter, and on the other hand, they didn't want to make this matter big, so they dealt with this matter coldly.
Yu Wan did not know that the Yu family had already found her biological mother's address and was preparing to bring her biological mother over to confront her.
Thus, Yu Wan had always been full of confidence for her future. In order to increase her chances of returning to the Yu Family, she chose a man with a good family background from among her many suitors. She was prepared to use her marriage with this man as a bargaining chip to make the Yu Family acknowledge her identity.
