"Wow... my sister is insanely cool!"

A Duke who can’t take his eyes off me. A dazzling, flawless older sister.

I thought I’d been reincarnated as the youngest daughter of a ducal family in a sweet childcare romance fantasy, a cozy world where everyone dotes on me.

"...Wait. This isn’t a childcare story at all!"

Turns out, the novel I possessed isn’t a heartwarming family story, it’s a revenge story. And worse, the person I’ve possessed is the villainous younger sister, destined to be destroyed by her older sister, the very woman I once killed in a past life.

"Uh... sister?"

If I want to survive, there’s only one rule, stay on my sister’s good side at all costs. And live as quietly, invisibly, and harmlessly as possible.

"I just picked it up on the way."

But... my sister is acting kind of strange.

"If you ever get cast out of the family, I’ll take you in."

And wait, who is this now?
