I have always wanted to write a story like this. They have known each other for a long time, been together for a long time, and been separated for a long time. They have the same classmates, friends, and past, but they have different futures. None of them stay still. They keep running on the road of life, only occasionally looking back and looking at the past. They meet new people, hang out with different people, and live different lives.
It's just that in this story, there are only two people from beginning to end. The encounters from now on are not encounters, and the stories from now on are not stories.
They spend their entire youth remembering only one name.
