My name is Li Tiancheng. I was an ordinary student about to start my second year of high school. Aside from having more nightmares than other people, I honestly couldn't think of anything I was better at than anyone else. Yet somehow, a strange person knocked me out. When I woke up, I found myself in a strange place. Even stranger, this world didn't seem to be the one I came from. I wanted to know why that person had brought me here, and I missed my family, so I decided to uncover the secrets behind this world and find out why I had come here.
At first, I had no intention of recording what happened to me there. After all, I wasn't even the kind of student who liked doing homework, let alone keeping a diary or writing down the details of my daily life. But the longer I stayed there, the more bizarre the things I saw and heard became. If I didn't write them down, maybe after a while I'd start to think it was nothing but a nightmare I couldn't shake off.
