At the top of the city, on the rooftop of Tianyu, a young man was sitting quietly in bear pajamas, holding tightly the latest and most popular new version of this year's iPhone in his hand. His eyes were a little distracted, as if he was looking at the sunset, and his eyes were red and bloodshot. Because his eyes were extremely wide open, they were filled with moisture. His eyes were empty, like a discarded rag doll. It was still very cold in Boundary City in early summer. As night fell, people on the road tightened their clothes and stamped their feet to cry out the cold. However, the boy just hugged himself tightly and shivered. From a distance, he looked like a lost cat, waiting for rescue alone. When you get closer, you can hear the young man murmuring in a low voice: "What I want has never been this world. I just want you to come back. I just want you. Xia Xia, I miss you so much." The person who once stood here said: "Yinan, you must remember that when I grow up, I will give you the best in this world."
