Ps:
1. I try to make the main text as cheerful as possible. This article is essentially a funny article. Because I found that I was too tired to write the article that I thought about too much, and I was not satisfied with it from time to time. I didn't know how to describe the feeling I wanted, so I wanted to write a funny article first.
2. There is no cp. The relationship between the protagonist brother and sister is purely family. Because they both have some psychological defects, their relationship is particularly close.
3. If you have any other questions, I'll write them after I've thought about it.
Intention: May you always have a companion in the world
