Xu Weilai could ignore and disregard what happened between Su Ziqian and Gu Yu. She also never intended to make a scene over Su Ziqian's repeated provocations.
After all, Su Ziqian was shocked to learn that Xu Weilai was suddenly married to Gu Yu. She wondered how Xu Weilai was three years ago when she was suddenly left, causing her engagement to be annulled. She also experienced such a terrible feeling before.
In the end, Gu Yu and Xu Weilai were not married; he never even acknowledged her as his official girlfriend. What right did Xu Weilai have to denounce Su Ziqian?
If Su Ziqian wanted to fight for Gu Yu's love, then she should've turned to him instead of her. The last thing Xu Weilai wanted was for her career to be ruined by Su Ziqian!
It was a nice coincidence that Xu Weilai could settle the current incident along with the Pang Hai incident and save herself the trouble of having to get even with Su Ziqian again!
