The temperature of the world for Jiang Xu has always been below zero.
So he learned not to expect, not to get close, and not to look back.
Cheng Yang's appearance was like an accident, making a lot of noise but couldn't be driven away no matter what.
Others call him "Jiang Xu", but he calls him "brother".
He was not afraid of Jiang Xu's coldness, he was just afraid that Jiang Xu would stay alone for too long.
"I will make up for the cold you suffered before."
"Wherever you go, I'll be there."
Many years later, Jiang Xu stood in the ginkgo rain at Tsinghua University and thought:
It turns out that there can really be light in the sub-zero world.
Intention: People who have been cold also deserve to have light.
