I’m The Devil’s Stepmother Who Will Soon Be Murdered

“Wanna kill or be killed?”

I possessed the body of an extra stepmother in a dark novel who gets brutally torn apart by a demon on the very first page.

Sinclair, an illegitimate child of a witch, lived her life being abused by her marquis father and her half-siblings.

One day, she’s given a mission: enter a political marriage with Grand Duke Gerald von Zeyer…

And win over his heart before assassinating his nephew—the young duke—before he awakens as a demon!

No way I’m going to step on the same death flags as the original Sinclair.

“Son, how old are you?”
“I’m five yearsh owd!”

Estimated survival time: five years.

I must break the young duke’s curse, raise him to be healthy and kind, protect my favorite character the crown prince, prevent the fall of the empire, and save my own life.

“Son, shall stepmom make you something sweet?”
“Son, want to care for stray dogs and cats with stepmom?”
“Son, should we join a study club together?”

Initiating “Young Duke’s Personality Development Project.”

“I’m gonna marryh my shtepmom.”
“Nonsense. I’m building an R-rated library and workshop where only we can be alone.”
“W-Why?”
“Because you’re mine.”

But…

The supposedly pure Grand Duke—who claimed he had never dated or married before—is now obsessively possessive.

Can I survive the jealousy of this clingy demon duke?
