Mo Xi knew Cayden and Valerie before Jing Mo Chen told Mo Xi about them.
Ellington met Cayden by accident when he was going to Country N for some work that Mo Xi had arranged for him. At that time, no one knew that Cayden was the King of Country N. So, they were all astonished when they saw each other, especially when Cayden and Valerie had thought that Ellington and Xue Yue had died under Mo Xi's gun. After that, Ellington then told Cayden what happened, and Cayden and Ellington got together. The four childhood friends started to talk and interact once again.
Mo Xi had told Jing Mo Chen about Xue Yue and Ellington as well and the fact that she knew about Valerie and Cayden because Ellington and Cayden were a couple. However, Jing Mo Chen never knew that Mo Xi had such plans with them.
Yang Zhen Ying's hands gripped into a tight fist as she felt that Mo Xi went through all those pain because of her.
