My Fox Spirit Girlfriend

How should I put it? I read this book a few years ago, but it was not about this software. It was quite interesting when I first read it, and I have finished it. When I was 22 years old, I wanted to look back and I changed my mobile phone software. It was different and I couldn't find it no matter how I looked for it. I was also upset. Now this novel should have been skipped, some of the later chapters have been moved forward, and many of them are missing. How can I say this? It's okay, right?
