This is a youth story that may happen to boys and girls in most northwest border towns. Lu Qing met him when he was 13 years old. He had a fair and crooked face, a sarcastic way of speaking, a crooked walking posture, and always tilted the corners of his mouth when he smiled, pretending to be bad, cynical and immoral. Lu Qing was not willing to look at him seriously from the beginning. It is better to stay away from this kind of person as far as possible. But what caused the two of them to get entangled in the same direction later on? Are they both ambitious and uninhibited in their desire for freedom, or are they both equally sensitive to every hair on people and things? The two of them seemed to want to get closer to each other, but how could two people who were too similar, who were too used to running away and avoiding each other, get closer without being too deliberate? If you can't get close enough, are you doomed to alienation and drifting apart? And how can we make the subsequent development less sad and lonely?
