This story is not long, starting from San Francisco in 2017 to Hangzhou in 2020.
Like all stories, it changes from yesterday to last year, and then slowly goes away and becomes the story of that year.

Just like the twists and turns in the story, if you happen to meet someone who looks like the person in the story, there will be an extra secret between you and me.
Purpose: The love we have when we are students are often unrelated. Later, when we grow up, we learn to bless each other.
