Great story of underdog. Really like how the MC is weak and becomes strong. Please continue writing, really like your work. Wish that he'd get even stronger.

I really really love this book. I can't stress how good it is. I love reading idol novels, and this is one of the best ones I've read. If you see this, then you should go ahead and read it.

I can't stress how good this book is! Well-written from the beginning, and the pacing is just right. I really like how he reluctantly does all of the missions for his sister, but ends up doing it with utmost sincerity. I hope there is more. Keep updating, author!

It's a really nice story with good world-building. The premise is quite interesting since the main character is a villain. Keep it coming! I hope you keep updating, author!
