The author is a university student, not a police academy student, and a fan of criminal investigation and mystery novels. Writing this novel is something of a hobby. Although I've picked up some writing experience from reading crime novels, when it came to actually putting pen to paper, I sometimes found myself at a loss for what to write. Readers, please feel free to point out any shortcomings, and I hope you'll share your suggestions. Your support is my greatest motivation to keep updating. Thank you, everyone!
