This is a story about a college classmate, and it can be considered a co-writing. She said it, I listened to it, I wrote it, and she accepted it. This is a story about a girl's first 20 years. Although it is plain and youthful, it is also a presentation of women's thoughts in a certain atmosphere in 2016 and their fantasies about the future. I changed her name to Chen An. Just like this name, she is plain, quiet, and has a hint of youth. I hope all my classmates at that time are well!
