A classic quote from a novel?
In this world, no one is indispensable because everyone has their own value and role. Once they lost control, they became extremely cruel, even if they were gentle and kind. Once a person becomes strong, they will lose their soft side and become cold and heartless. People are kind by nature, but in some cases, people will hurt others to protect their own interests. The most painful thing in the world is to lose. Even if it had been lost, it could never be retrieved. There is nothing more important than losing something in this world because it will make you understand that everything you once had was fake. Everyone has their own secrets that they don't want others to know or recall. The furthest distance in the world is not the distance between life and death, but when I want to tell you but you don't know. In this world, nothing is eternal, only a moment is precious. The darkest place in the world is the human heart. Because the human heart was the darkest, cruelest, and most heartless.
