a person's business

This is a short story I wrote about three years ago when I was still in college.Because of professional issues, all novels written after college will have some narrative pictures instead of descriptions of internal situations.So when reading, it will be easier to read when you link the pictures in your mind.The entire novel is less than [-] words, and I decided to post it after making some simple corrections.It's worth a look.As for this very simple title, I also forgot why it came up like this in the first place. In short, it has not been changed. Let's respect the author's intention three years ago.The story is simply a story of a killer and a cop living in the same building.
