Today is April 27, 2024, the 568th day since she left this world. I miss her often. This is my first time writing a book. Thank you for reading. This book is adapted from a true story. Every character in the book has his prototype. The protagonist Xia Xiaoyu is one of the most important friends in my life. On countless sleepless nights, I blame myself so much for not finishing our chat with her that day, because I haven't finished talking, because I still have a lot of regrets, and because my life is not happy, so I decided to write about her. In the book, I will let her get all the persistence and pursuits in her life. There will be no harm or betrayal in heaven. I think she should be happy. I would like to dedicate this book to all those who bravely pursue love, but please remember: life is precious, love your neighbor first and love yourself first. I wish you and me all the best.
