Xia Xuanmo was a person who paid particular attention to being watertight, and everything he did must have a purpose.
Since the Xia and Tang families had proposed a marriage alliance, the first thing he had to consider was what benefits this marriage alliance could bring him.
When it was confirmed that the marriage could be carried out, he would investigate what kind of person Tang Ziyu, who was going to be his wife, was.
It didn't mean that if Tang Ziyu's character and virtue were not good, the marriage would not be terminated.
Instead, knowing what kind of person the other party was would make it easier for him to manipulate the other party in the future.
Therefore, Xia Xuanmo knew some of Tang Ziyu's past, which was also a very wonderful story.
