When Zhi Bing was 5 years old, she moved with her mother and met Zuo Xiang, the neighbor across the street. Zuo Xiang became the first person that young Zhi Bing fell in love with. Zhi Bing once naively thought that she would be happy with Zuo Xiang for the rest of her life. When Zhi Bing was 13 years old, Zuo Xiang suddenly and mysteriously told her that he liked her. After falling in love with a girl who smiled like a flower, Zhi Bing's heart suddenly felt empty, as if her most precious thing had been taken away by someone else. Because of this, she hid in an uninhabited corner and cried in the dark so many times. She hated the girl named Yimei, who had robbed Zuo Xiang. It was obvious that Zuo Xiang really liked her, so Zhi Bing left without saying goodbye and left silently. When Zhi Bing returned to the city at the age of 23, nothing seemed to have changed. Zuo Xiang was still the same Zuo Xiang, and Zuo Xiang was also the whole meaning of her life.
