Regarding memories, I used to cherish them very much. Later, when I went to college, I occasionally heard someone say something, and I believed it deeply. She said: "Memory is a book that has been turned over." Yes, since it is a book that has been turned over, then, allow me to make slight changes, so that I can occasionally sink into the world I weave. Memory is your own, why do you need to remember the unbearable past events one by one and make yourself miserable?
