Huo Tian was indeed very angry when she heard that Ding Rong wanted to acknowledge Huo You. Actually, if she had just given it a little thought, she would know that this was impossible.
Before Xi Cheng appeared, Ding Rong was only a single mother. It was normal for her to be unwilling to part with her adopted daughter, who had been with her for 18 years. If the elders of both families were generous and kind, letting the two children who had brought the wrong child acknowledge each other as their godparents would be a wonderful story.
However, when the two families switched back their children, things had gotten too ugly. Ding Rong wasn't a senseless person. Even if she still couldn't bear to part with Huo You, considering Huo Tian's mood and the Huo Family's style, she still cut off all contact with Huo You in terms of her feelings and actions.
