Last year at this time, Yu Xinyan was still at summer camp, while Xu Lin was typing at home.
A year passes in the blink of an eye.
Yu Xinyan felt a bit sentimental. Originally, there was nothing for Xu Lin to feel sentimental about, but Yu Xinyan's mood influenced him, and he suddenly felt a bit lost.
Why?
Xu Lin thought it was probably because he had grown up.
At nineteen, in ancient times, he might have already had a son.
Therefore, Xu Lin had more things to face, like thinking about how he should live his life or dealing with all kinds of mundane matters.
Time passes, and the night is about to fall.
Seven thirty.
"Xu Lin, I have to go to class."
Yu Xinyan felt a tinge of regret, reluctant to part.
"Which classroom?"
"The laboratory building."
"I'll walk you there."
Xu Lin and Yu Xinyan went together to the laboratory building.
"Here we are, go on up. If anything comes up, you can call me."
Xu Lin reminded her.
"Okay!" She nodded seriously.
