On the night when Gu Siyu attended the funeral of his grandfather Gu Zhiyuan, he received a letter from across the ocean.
The sender Shen Yanran said that he found more than a dozen old unsent letters among his grandfather Shen Xingzhou's belongings, and the recipient of all the letters was Gu Zhiyuan.
Gu Siyu thought he knew his grandfather well enough, until those letters spanning half his life were delivered to him.
As the old letters unfolded one by one, the two young people followed the words in the letters and pieced together the unspoken concerns of the two old men when they were young.
And what Shen Xingzhou and Gu Zhiyuan failed to do, their grandchildren have done it.
