[Try mentioning Grey in front of the Emblem crest.]

The two families that appear in the most beloved proverb of the Lutinas Empire are notorious enemies known throughout the land.
Among these two prestigious swordsmanship families, I was reincarnated as Sersia Emblem, the cherished jewel of the Duke of Emblem’s household.

After living a brutal life as a detective in my previous life—only to be killed by a criminal—this new life felt like a reward, sweet as honey.
But then…

“You’re going to become pathetic.
Both you—and the Emblem family—will grow weak.”
“Say that again, you bastard!”

I ended up getting engaged to Enoch Grey, the heir of the Grey family, whom I had fought, clashed with, and competed against since we were infants—like sworn enemies to the bone!
All because of our mothers’ scheme to reconcile the two families.

Engaged to Enoch, with whom fists and swords flew every time our eyes met?
Arriving at the engagement ceremony wanting to bite my own tongue, I instead ran into an unexpected ill-fated connection.

“Didn’t you miss me, Detective?”
“Don’t tell me—!”

My present-life enemy Enoch Grey was also my enemy from my past life.

After awakening his memories of our previous lives, Enoch began trying to claim the seat beside me with a sickeningly sweet voice and half-crazed eyes.
His change slowly started to disrupt the calm world around me.

“I didn’t stand by all this time just to let Lord Grey steal even your heart.”

From my liege, the Crown Prince…

“I endured it because you said it was only a formal engagement.
But I cannot accept you wavering because of Lord Grey.”

Even my lifelong aide began openly showing hostility toward Enoch.

And yet, the one who torments me the most is—

“After you died like that, Detective… you have no idea how insane I became.
Sersia, you really don’t know.”

Enoch Grey.
My enemy in my past life, my rival in this one—
and the man I can’t escape.
