The whole text has been overhauled. I am now in my first year of high school. This is a text written in junior high school. Now it looks really... I stopped updating for a long time because I can't write and I don't know how to write. I am afraid of breaking the children. Now all my thoughts have been sorted out and the title of the text has also been changed. I will post it when I finish it.
Ps. The update is still uncertain.
