As A Maid, I Can Fix Her!

Trapped in a past mistake, I tried to make up for it by writing another story that would atone for my mistake. 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!
