This is a true story, and the characters choose online names.
When Xu Si was 11 years old, he got to know Yuan Dan and made a friend named Sheng. They gradually became familiar with each other, from strangers to lovers. The story is not necessarily written exactly according to the events. There are some reductions and some additions.
I don't want to update anymore, the update time is uncertain
Intention: Nostalgic for Xu Si and Sheng
