The purpose of writing this article is very simple, I just want to do something for that gentle boy who thinks about his sister. When I saw that Nunnally didn't understand him either, I really wanted to give him a hug and tell him that I am here and that everyone in front of the computer or TV is here. Lulu's eyes make people feel distressed. On impulse, I wrote the ending of this article. The back desk said it was well written, so I wrote the article. I hope everyone likes it.
