Due to some special reasons, a certain book is not effective, so I plan to give up...
Ah, of course the above is bullshit. In fact, it is just a boring excuse I made for myself simply because I wanted to open another book. I don't want to say more, I just have nothing to do when I have nothing to do. In short, you can read it as a postscript to my last book.
Having said that, this can also be a "Back to the Future 1999" fanfic, but how did I choose the tag in the first place? Well, worth pondering
