Prologue

One day I gain my memories of my past life and...
Hm? My adorable younger sister is the heroine of a fantasy novel? And I, the jealous villainess must make her life hell, so that one day she can be saved by her princes?
How can I bring myself to hurt my fluffy bunny?
But... I must.
For her happy ending, I will brave the role of a villainess.

... That's good and all, but why isn't it working?
