If I were to list my favorite stories from my works so far, "The Precision of Death" would definitely be one of them.

It's raining again. It happens every time I work. I've never seen sunny days. My job is simple. According to the information provided by the Intelligence Department, I have to chat with a selected person, spend seven days with him/her, decide whether to "yes" or "let go", and inform my boss of the result.
