Shen Wangxi and Zhang Xiangze have been in love for five years, starting from a note in the university library.
On the eve of the anniversary, the two of them tacitly hid a surprise - Shen Wangxi held the engagement ring engraved with each other's names and wanted to take Zhang Xiangze to the city to get the certificate; Zhang Xiangze checked the guardianship information and looked forward to taking his lover to the notary office in the early morning.
But a sudden air crash kept Zhang Xiangze in the cockpit forever and became a hero who saved hundreds of people, but he failed to fulfill his promise of "see you in the evening".
With the unsent ring and 147 letters full of longing, Shen Wangxi walked through every place on the two's wish list - he counted the lonely footprints under the aurora in Norway, and he left half of the unfinished vanilla ice cream in Santorini's sunset.
Two years later, he chose to follow his lover and just wanted to be buried next to him. But due to the cemetery's regulations and cold laws, a ten centimeter cement wall was built between the two tombstones. They had crossed thousands of mountains and rivers across life and death, but in the end they were separated by a thin wall and could not even embrace each other's ashes.
That wall is the guardianship that was agreed upon before there was time, the unspoken proposal of marriage, and the most painful regret of being in love for a lifetime but not being able to share the same hole in the end.
