I Just Want to Be an Ordinary Writer

Kira Yoshikage, 19 years old, is a college student.
My dream is to become an ordinary writer with a lower middle level. I don’t need to compete with Shiyu of Kasumigaoka in sales, and I don’t need any illustrations by Mr. Erromanga. I just want to earn money without leaving home. Money to live a peaceful life.
One day, Yoshikage Kira, who was rejected for the manuscript, witnessed the crime of the beautiful girl serial killer in an alley - Yoshikage Kira knew what to write!
As a result, a common reasoning novel with a serial killer of a sickly beautiful girl as the protagonist was successfully published.
The first day after publication: "Mr. Kira, according to the details of the crime in the book, we have reason to suspect that you are the serial killer, please come with us."
Kira Yoshikage: "?"

A reporter: "Mr. Kira, I heard that you accepted the challenge of a serial killer and successfully caught him!"
Kira Yoshikage: "You are mistaken, he just exploded on the way to kill me."
reporter:"?"

"Congratulations to Kira-sensei for winning the first place in 'This light novel is amazing!'"
Ji Liang Yoshikage: "Do you understand what ordinary means?"
