Yu yi was the kind of person their parents wished their children to be. Yu xin was to live for themselves, to have no fear, to freely express what they wanted to be. No matter what, they were all one person. Many people are like this these days, either because they are living for their parents or for others, or because they are hiding their true self deep in their hearts and unable to express it. In any case, we are all living in this world, so try to live for ourselves. Life is not to be a better self, but to be yourself.
