The beginning of the story is that they met in that midsummer and met in that river. Qin Mo's father's words may be a prophecy. That sentence ruined his youth and revealed his future, and the prophecy came true. When Qin Mo was 18 years old, the proud man of heaven fell from the altar and jumped into the river where they met. From then on, there was no such proud man of Qin Mo in the world. And Xie Chen, the smiling top student, also died on the 520th day. Holding his ashes, he said the words he had buried in his heart for a long time, and jumped into the river. The story ends with the river being the intersection where they met and the tombstone where they were buried.
Intention: Understand that youth does not necessarily have to be flamboyant, and there is also sadness in parting.
