Sheng Jiahe always brings unexpected surprises to Chen Yu.
13-Year-old Sheng Jiahe wrote in the last sentence of his farewell letter: "True feelings, words from the bottom of my heart!... It's weird, so I added a sentence of my own. The above is selected from the collection of essays!"
When 18-year-old Sheng Jiahe met Chen Yu again, he used the most clichéd words: "Brother, have we met somewhere?"
The 24-year-old Sheng Jia had a "serious" conversation: "Three billion galaxies collided as promised. The universe is tragic and spectacular. I miss you the most... It can be said that they are unrelated love words, so I can only say: The east is not bright and the west is bright. I am like your father!"
He knew that this person who always surprised him couldn't do anything serious.
But there are exceptions. Once, Sheng Jiahe, who was completely drunk, crawled on Chen Yu's back, whispered into his ear warmly: "The moon under the sea is the moon in the sky, and the person in front of me is my sweetheart. The little moon, the gentle starlight, I love you most..."
Later, Sheng Jiahe's thoughts were scattered, as if he heard a sentence: "The stars are passing by, but my love for you remains unchanged..."
(The meaning of the novel's title is: Space vectors were originally the content of science and mathematics, but were added to liberal arts mathematics in the new curriculum standards, just like the intersection of two people's destinies!)
Intention: Study hard for me!
