The story takes place in Qingcheng No. 9 Middle School. In the second year of high school, art student Zeng Xinyue and science top student Zheng Zhuoheng met by chance, and they developed feelings for each other through frequent exchanges. The two officially fell in love in their senior year of high school, but their early love was discovered by the school and their parents, and they were forced to go underground. After the college entrance examination, the two went to different cities to start a long-distance relationship. The long distance and conceptual conflicts continued to break out, and they finally broke up.
After entering the society for many years, the two met again in the workplace in Qingcheng. The knot in their past slowly untied, they chose to be together again, and they had already discussed getting engaged. At this time, Zeng Xinyue was diagnosed with a terminal illness that was difficult to cure. In order to prevent Zheng Zhuoheng from suffering pain, she chose to disappear completely. Zheng Zhuoheng spent several years searching everywhere but found no clues. After a long time, he received the news that Zeng Xinyue had passed away alone. A love that started in childhood ended up being separated forever, leaving only eternal regret.
Purpose: Loving each other does not mean staying together. Regret is the normal state of life. The impermanence of fate far outweighs all the efforts between people.
