The kingdom’s hero, Valen, can’t stand the very mention of demons.
On the battlefield, he tried to save a woman who was about to be attacked by a demonic beast—only to be struck from behind and lose consciousness.

And when he opened his eyes…

He was in the middle of a forced wedding ceremony in the Demon Realm—with the very woman he had saved!

“I am Arhen. And you are?”
“As if I’d tell my name to some filthy demon.”

The woman Valen rescued was Arhen, a high-ranking demon believed to be a succubus.
Worn down by years of war, the demons propose a marriage alliance to him.

“As you can see… I’m the type who gets wet easily.”

And to make matters worse, the deal doesn’t end until Arhen becomes pregnant.

A human hero with a hatred of demons, Valen, and the Demon King Arhen, who wants to protect peace through pregnancy—
can their newlywed life ever be peaceful?
