"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....
