I Discovered the Duke’s Dangerous Secret

Synopsis

A world ruled by mages.
In this world, those who cannot use magic are called “Notch” and are doomed to live a lifetime of contempt and discrimination.

I was reincarnated into such a world.

And of all people, I became a tragic noble lady—born with magical power, yet unable to use magic because of a weak heart!

With a special ability I happened to acquire, I desperately tried to heal my heart and escape the shackles of being a “Notch.”
But then—something completely unexpected happened.

Instead of finding a way to heal my heart, I uncovered a dangerous secret of a man who had become the strongest in this magical world not through magic, but through the sword.

I barely escaped from him as he tried to kill me and fled back to the estate, but…

Why is he here?

“I heard you ran away after receiving my proposal. I’m glad we could finally meet like this today.”

The man before me is Duke Rektarion Eden Northdian—
known as the “Mage Hunter,” a figure of terror among mages, and the only Aura Master on the continent.

And he has proposed to me.

“Oh dear. Do you dislike me that much?”

With an expression that looked neither fully angry nor fully amused, he shrugged his shoulders once.

I squeezed my eyes shut and dropped a bombshell.

“I’m sorry, Duke. I have no need for a Notch husband.”

What will become of Eloah, the heroine who has learned the Duke’s secret?
