One Day, My Fiance Demanded to Break Off the Engagement

⌜Please forget about your ailing fiance and begin a new life, my lady.⌟

One day, a letter arrives for Adeline announcing that her fiance has been given a terminal diagnosis.
However.

“Now that leech will finally let go.”

In reality, it was nothing more than Noah’s spite, as he simply did not want to get married.
Noah, an arrogant and dissolute duke who yearned for a free-spirited life.
Noah believed his plan was perfect. If he could only break off the engagement with her, he could endure anything.
If there was one thing he overlooked……

“I will stay by your side and watch over you until you have fully recovered.”

That Adeline, a woman so conservative she was almost quaint, could come running to him in an instant, and,

“There will be no breaking off the engagement until you are dead.”

That she was an absolutely insane woman.
