I Became the Nanny of My Future Villainous Stepdaughter?!

Reincarnated into a novel destined for a bad ending...? And my role is the Nanny who gets killed first by the villainess?!

Ayaka Musashi, a former nursery teacher, is reborn as Aria in a world where a young girl named Fia lives, a child who will eventually grow up to become the villainess who destroys the empire.

Aria is given only one mission in this world, to serve as Fia’s nanny during her childhood, shower her with love, and guide her onto the right path before she becomes a villainess.

As Aria earnestly cares for Fia, her sincerity gradually begins to change even the girl’s adoptive father, Proud, the dark mage feared as the strongest in the empire.

Before she realizes it... the girl who was supposed to become a villainess grows attached to her, and the supposedly cold-hearted Proud starts closing the distance between them.

"Why am I, the Nanny, the one being showered with affection?"

The supporting character who was supposed to be the first to die begins to be loved instead, a hardcore childcare fantasy like no other!
