Analyze the emotion of this song. Let me tell a story first. A cynical boy, in his early twenties, met a beautiful girl. Two people work hard and naturally get together soon, but boys always feel that there is a distance between them and girls, or that they are concerned about different things. One likes entertainment, the other likes poetry, and finally accidentally broke up because he felt incompatible. Girls become women, boys become men, and women want to get married. When she got married, the man secretly congratulated her. It's sad to see a woman not laughing. Men grow up at this time, sometimes recalling that they broke the girl's heart and gave her the best promise, but they never got into her heart and understood her feelings. A man always thinks he is kind and has the heart to save the world, but when he sees a girl like this, his heart is very distressed and he always thinks it is his own fault. The more he thinks about it, the more he regrets it. Women mature earlier than men. At this moment, men are distressed.
