The Female Lead Became My Sister

This story is on hiatus for now, but I'll definitely finish it someday. I transmigrated into a book I was reading. The logic was predictable, the plot was cliche, and I had no doubt that my existence in this world was abnormal. Maybe my fate was already set. Maybe someone was watching me even now. So, before the inevitable arrives, I need to prepare to fight it. Even flowers that grow in hell yearn for the sunlight in the sky. Reborn female lead--villainess (No CP) I transmigrated into the story in my own body. It gets pretty angsty later. The logic is that there is no logic. Theme: Hard work pays off
