Primordial Sin System

Hello dear readers, the author here. I apologize if I cannot post new chapters because I have many things to accomplish for my schoolwork and studies, and I often stay up late to finish them. My tests and quizzes are also approaching, so I cannot find the time to publish new chapters. I hope you understand, and I promise that after this, I will mass-release new chapters. That's all, and thank you for your support.
