Su Lu and Yu Sheng went to the same high school and the same university together. . .
The two people seemed to be dependent on each other, but also seemed to repel each other.
In high school, he was next to her, a top student in the science class and a poor student in the liberal arts class. . .
He said: "Hello, my name is Yu Sheng."
In college, he was still the top student in the school's best major, and she was the lucky one to catch the last train. . .
He said: "What a coincidence, you are here too."
Later. . .
Su Lu, what identity will you take when you see him again?
Classmate? Friend? Passerby?
How will you feel?
With smiles, with tears, with peace. . .
Su Lu, what would you say to him?
Please give me more advice for the rest of my life.
Please take care of yourself for the rest of your life.
Please don't see me again for the rest of my life.
