And it will never change.
It was precisely because Chu Tianyang understood these things that he reminded his sister with his words, never to do such foolish things. If she harbored such thoughts and took actual action, then the Chu Family would have to bear all the subsequent troubles for Chu Yaoyao.
His declaration of wanting to leave or "return his freedom" also showed that he understood the principle that it wasn't wise to block every exit. If he continued to suppress Chu Yaoyao, it would only drive her to extremes. It would be better to wait until things in Jingcheng settled down and the Chu Family was no longer at the eye of the storm; then they could simply send Chu Yaoyao abroad, and all problems would be solved.
