The kingdom’s hero Valen is so infamous among demons that they shudder at the very mention of his name.
While 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?”
“Why would I tell my name to a filthy demon like you?”

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

“As you can see… I get wet easily.”

Worse still, the deal doesn’t end until Arhen becomes pregnant.

Valen, a human hero with an intense hatred of demons, and Arhen, a Demon King who wants to protect peace through pregnancy.
Can their newlywed life ever be peaceful?
