A tragedy caused by a notebook(?).
*This notebook is not that diary! Not Riddle!
To put it simply, the story took a big turn because of a small mistake on the night when Harry was eleven years old.
Harry: Hey, why is this notebook full of square words that I can't understand? !
Pooh: Damn, my notebook is all in English!
Notebook: As a notebook that connects two time and space and is mixed in Chinese and English... I have a long way to go :)
[The character belongs to JK, the ooc belongs to me, please be gentle qwq]
