Opened Book

I am an opened book with secret pages inside.
You think you know everything, but trust me, you don't
I am an opened book, written with strange codes
You can see what's inside, but you can't understand a word of it

I am an opened book, with a very long and complicated story
Reading a few words from it, will only confuse you. Then you'll stop reading it immediately.

I am an opened book, with random pages.
It's so difficult for you to follow the story.

I am an opened book.
you don't have to ask, I will tell you my story.
but if you feel like it's boring, or confusing,
just throw it away.
