"I......I never thought about it. How did you know?"- Dong Hyeon astonishingly asked. "Easy. The page of the teared-up book was different in the book that all of us see that we get from GreenLeaf Corp. Building days ago. This paper was a modern type of the A4 Page, one of the branded papers that has been introduced to the public for 4 years ago. We can all compare and contrast it to the old page, let me just demonstrate for a moment"- Kyung Rim explained then went to the truck to get the book. He flips the page and let us all touched it first.
I see, it was also been set up. Man, I was also fooled by the pages. Impressive!
