Undercover Agent on the Peninsula

Honestly, this book of yours is still a bit cheesy. The first chapter is a bit too explicit. The protagonist's character and background are reminiscent of old-school K-pop from ten years ago. It feels like a clichéd story of a special forces infiltrator fighting against a conglomerate. Given your previous book, "Single Yoon-ah," your writing style is really not good enough for this kind of plot.

This is the author's third book; it should have had an outline, not have been written on a whim. The timeline is 21 years old in 2013, five years of military service followed by discharge, and then joining SM Entertainment at age 16 six years prior. He was a trainee in 2007-2008. And since it's related to trainees, does that mean the female lead is f(x)? Or maybe Girls' Generation at most?
