At the beginning of the story, Mu Xiaozhou gave Jiang Hai a painting of his own. The person in the painting was Jiang Hai.
They became roommates and they liked each other, but Mu Xiaozhou confessed her liking and Jiang Hai restrained his liking.
Jiang Hai always felt that there was still time to explain, but the separation was unexpected, and Mu Xiaozhou's goodbye was never seen again.
For many years to come, Jiang Hai would dream about Mu Xiaozhou, but never heard from Mu Xiaozhou again.
One dark night, he dreamed of Mu Xiaozhou again, so he finally mustered up the courage to turn on his cell phone that he had turned off a few years ago.
Looking at the news above, Jiang Hai felt that his illness was getting worse. It turned out that the goodbye was just to save him.
"Jiang Hai, let's elope."
Later, he met Mu Xiaozhou at his friend's wedding. She was no longer her, but she was still her.
She said: "Long time no see, Jiang Hai."
He said: "You are well, Mu Xiaozhou."
