Knife
(Since it is my first time to write an article formally, it may be a bit rough. I write based on my feelings, and I also ask my friends to help me evaluate it. The names of the characters may not be very good, and the names are really difficult to choose. There will also be bad writing or typos. If there are any mistakes, you can comment. I will try my best to read the comments. Maybe I am not good at writing, but I can at least understand the words in other people's introductions. I'll give it a try, please don't complain!
Intention: I don't want to lose it
