I became the sister of the villain, who shed no blood or tears in a war-ridden novel!
I thought I was born again as the youngest daughter of a noble family, but I'm the little sister of a villain who's only being used!
A baby's body too fragile to survive in the Lagrange household, a brutal family that makes children fight for successors... I've decided to stick to the villain in order to live!
I need you to be my guardian until I run away from here. Raise me, villain!
