Originally, I said this sentence as irony. It was said by a man of heart. A person with a heart will only hope that he can be ruthless when he is hurt. Then this sentence, in turn, means that if I have the heart, the world will not be wonderful. The feeling of "beauty" mentioned later is aimed at a person or a thing he cares about. So long can be understood as, if I am too hard on a person (or a thing), it will make her unhappy, then on the other hand, I will become concerned about you and your life will be wonderful, so be happy. Give up yourself and be happy with her is a word. If you can't give happiness to the person you love, let him find his own happiness, forget the past mercilessly, and feel like a comforting word after being sad! That's what self-feeling means. Hey hey! ! !
