This is a true story. The protagonists of the story can be said to be very sad. I sighed for a long time. For this reason, I decided to write this story for them. I don't know if anyone will like it, but I know that if I don't record it, I will regret it for the rest of my life. ． ． ． Their bond with each other and their love for each other shocked me. I didn't know whether the girl's choice was right or wrong. I only knew that she died without regrets. ． ． ． I write this article in the first person. My writing is not good. I try my best to describe the emotional entanglements of the characters. I hope everyone can understand them. In this book, for fear of involving the privacy of the parties involved, all the years, locations, and names have been changed. Please do not delve too deeply into it.
