A mistake... which I had created tragic stories for each of the Villainess girls, who died horribly, to serve as stepping stones for the main character's love story. In my dying moments, I transmigrated, taking over the body of a little girl I didn't know. Without knowing anything, I found myself trapped in the world of my novel. With this, the Happy Ending rescue operation of the Villainess girls begins! — Description from novelcodex.org
