The First Half of My Life Was Always Full of Regrets

This is the first time I want to seriously write a novel. The first half of my life has always been full of regrets, so I want to write it down. I don't know whether this book will be published in the end, but I decided to write it down. This novel can be regarded as a prequel, and there may be more in the future, right? I hope no one has the same story as me. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
