They Say an Age Gap Like This Doesn’t Even Need Matching

At the dawn of the Kingdom of Bardia, Iserna Airvayne leads an expeditionary force to conquer the “Black Rift,” the realm of demons.

After years of war, she finally emerges victorious. But when she uses return magic, the place she arrives in is none other than the world 300 years in the future.

“What are you? And how did you get in here?”

The man who mistakes her for an intruder after she suddenly falls right on top of him—and even goes so far as to propose marriage—is Elhardt.

He is the deposed Crown Prince of Bardia, held hostage in the imperial palace of an enemy nation.

The kingdom she fought so hard to establish is already on the verge of destruction.

And to make matters even more confusing, there is Auriel, the Crown Prince of the enemy nation, whose face is identical to that of her old friend and the founding king, Mikhail.

For now, she has to save her dying kingdom and secure the rewards promised to her expeditionary force and their descendants.

And naturally, the traitors and turncoats who betrayed their country must pay a harsh price.

But in the midst of it all, Elhardt keeps shaking her heart without giving her a moment’s peace.

“I think my ideal type has always been someone older. Maybe around three hundred years old.”

At first, it was cooperation.

Then, it became “practice.”

And finally…

They became each other’s lives.

A knight commander who has returned after crossing three hundred years of time, and a man destined to become king.

The most dangerous alliance begins—a desperate struggle to reclaim a kingdom on the brink of destruction.
